As a widely applied method in many fields, parametric design is now finally exerting influences on architectural industry with the rapid development of Internet technology. For this reason, parametric architectural design is studied in this research based on optimization method. First, parametric design and optimization algorithm are introduced; then, the process of modeling and optimization procedures is discussed; at last, the parametric optimization design is applied to solve the complex architectural design problems. Parametric method will thoroughly affect architectural industry. Therefore, architectural designs should be based on optimization algorithm using parametric design to improve the progress and quality of architectural design.

This paper aims to investigate liquefaction hazard assessment criteria available in practice which are obtained by geotechnical tests. In this study, developed indices for evaluation of liquefaction potential of susceptible soils under earthquake excitation were analyzed. From basic physical engineering indices resultant from in-laboratory investigations such as grain size distribution curves to the more sophisticated in-situ tests such as Downhole, standard penetration test (SPT), cone penetration test (CPT) and piezocone modified (CPTu) test, developed criteria were studied. Subsequently, liquefaction potential index (LPI) based-criteria for quantification of relationships among applicable in-situ tests were discussed. Finally, in reference to the data presented in this paper, appropriate methods such as geologic hazard mapping were suggested for further visualizing of coupled analyses with the aim of providing practical instrumentation of geological maps in liquefaction hazard assessment.

Recently, a flood disaster is occurred in Cintaratu Village, Parigi Sub-district, Pangandaran Regency of West Java Province. Geomorphologically, the watershed systems of this area consist of Cintaratu, Selasari dan Cintakarya. Geologically, the study area is composed by calcarenite, reef limestone, and clastic limestone which is susceptible to dissolution when contact with the water. This research was conducted to investigate the causes of flood disaster based on the correlation between quantitative geomorphology and groundwater level analysis. The methods for this research are field observation and studio analysis. Field observation were conducted by hydro-geological mapping to determine the groundwater level and, also, the lithology of the surrounded area. Studio analyses include the calculation of Bifurcation Ratio (Rb), Drainage Density (Dd), and Fault Fracture Density (FFD). Based on Bifurcation Ratio calculation, the value of Rb1-2 of Cintaratu, Selasari, and Cintakarya Watershed respectively are 2.8, 6, and 3.5. Generally, Cintaratu Watershed has the lowest Rb value, and thus has the highest potential to be flooded. Groundwater flow map shows that the stream accumulation zone is located at the center due to topography controlled, thus allows water to accumulate. The average elevation of groundwater is is 111.3871 masl, however, the the average elevation of the ground is 117.4706 masl. The difference of both value is 6.083529 m. This shows that undersaturated area between groundwater elevation and ground elevation is low. So it can be concluded that, the main causes of flood disaster either from above or underground can be investigated by the correlation between quantitative geomorphology analysis and groundwater level.

Effective fleet management in surface mining is crucial to optimize the cost of surface mining. A complete method to determine the match factor for heterogeneous excavator-truck combination at Merit Pila Coalfield, Sarawak will be presented in this paper. This application is a fast and easy way to quantify the effectiveness of the fleet in mining. The match factor of 1.09 was obtained and proven by observation with the queuing length of one truck at one of the excavators. This result is crucial for the mining engineers to quantify and evaluate the existing performance and plan for more effective excavator-truck combination and scheduling in the near future.

The study area is underlain by the ultrabasic rock of partly Sabah Ophiolite Complex of Cretaceous ages. The objectives of this study are to determine the Q-value and to estimate the permanent support measures for 20m span, 10m high and eastern direction of the proposed tunnel in the study area. Engineering geological mapping (lithological and surface mapping and discontinuity survey), laboratory study (petrographical study) and testing (Uniaxial Compressive Strength testing) and data analysis (stereographic plots, Q system parameters evaluation and support estimation) was used in this study. The results shows that the rock mass is classified as lherzolite, strong, excellent quality, more than four joint sets, slightly altered discontinuity wall, dry excavation and favourable stress condition. The equivalence dimension (De) are 15.4 for the permanent roof. The Q-value for permanent roof and wall of the proposed tunnel are 1.4 (Class D or poor and type 5) and 3.5 (Class D or poor and type 3), respectively. The permanent and temporary supports for the roof and wall are systematic bolting, 700J energy absorption of fiber reinforce sprayed concrete, 9-12 and 5-6 cm thick fiber reinforce shotcrete, respectively.

Debris flow remains as a damaging natural hazards in the Crocker Range of Sabah, Malaysia. This is due to the fact that it can move at high velocity and longer travel distance, bringing big volume of sediment. One of the most severely affected area due to debris flow in the Crocker Range is that at Jalan Penampang-Tambunan KM 38.80 in Ulu Moyog situated in the district of Penampang. Recurring events of the debris flow from the year 2012 until 2014 have rendered the major road trunk between the west coast and interior region of the state impassable to traffic for hours. Nevertheless, the study on its behaviour in terms of velocity, discharge, and travel distance is still limited to the best knowledge of the authors. Therefore, the objective of this study is to identify the behaviour of the local case of channelised debris flow at Jalan Penampang-Tambunan KM 38.80. Based on site inspection along the channel and computation of flow behaviour by using established equation, the study finds that the velocity, discharge, and travel distance are controlled by the various channel parameters such as the elevation, width, depth, and longitudinal gradient.

The Middle Miocene sedimentary faciess classified as the Lambir Formation at Tusan Beach and Lambir Hill is revealed as tide dominated with exposed minor wave regimes association. Evidence of wave dominated facies is displayed mostly on shoreline deposits, such as planar cross stratified (PcS), swaley cross stratified (ScS), swaley-Hummocky cross stratified (SHcS) and hummocky cross stratified (HcS). The facies analysis reveals four facies associations, namely; foreshore facies association, upper shoreface, middle shoreface and lower shoreface. Whereas, tide dominated regime resulted three major facies association: tidal sand bar (TSB) facies association, tidal sand flat facies association (TSF) and subtidal mud flat (SMF). TSB facies association was developed from tide influenced shoreline that represented by herringbone cross stratified sandstone bed. The occurrence of herringbone cross stratified and other tidally structures within same facies explain that the current activities are in reversal process (flood and ebb). TSF and SMF facies associations, are widely distributed in the central Miri region including part of Lambir Hill and the Nakat River area. Wide exposure of frequent heterolitic beds, suggest that the Lambir Formation was deposited within the tidal flat environment.

This study focuses on the influence of weathered rock’s microstructure and its effect to the stability of slope at the Trusmadi Formation. Trusmadi Formation (Palaeocene to Eocene age) had experience a slightly metamorphism process and makes it highly susceptible to instability. Regional metamorphism that happened during tertiary has given rise to the formation of argillaceous rock. This rock then suffering a weathering process that change them to soil. Four samples were collected based on fail slope and stable slope. These samples were analysed using polarizing microscopic and scanning electron microscopic (SEM). Microstructural features identified that all slopes had the same platy minerals and mineral grain size and shape except for the cracks and porosity percentage. Percentage of cracks and porosity in stable slope are 35% and 40% in the average while 55% and 65% in fail slope. For SEM study, the percentage of porosity is 37% for stable slope and 55% for fail slope. The presence of 1:1 clay that is kaolinite gives only a small impact to slope stability.
