Abstract -- Taiwan is located in western branch of the Cum-Pacific Seismic Belt, therefore earthquakes occurred frequently in Taiwan. Under strong earthquake shaking, the liquefaction of sandy soils of alluvium and reclaimed lands in western coastal area of Taiwan may occur, which may cause damages for coastal and harbor facilities at this area.
This project is divided into five subprojects:(1)Seismic Wave and Excess Porewater Pressure Monitoring at Taichung Harbor Area. (2)The Study for Local Models of Liquefaction and the Risk of Liquefaction at Harbor Areas. (3)A study on soil structure of Taichung Harbor Area. (4)Measures against Liquefaction and Ground Improvement at Harbor Area. (5) Ground Subsidence Monitoring of Harbor Areas.
