    摘要: Taipei Basin, the political and economic center of Taiwan, is underlain by soft alluvium soils that may be susceptible to soil liquefaction and the hazard of lateral spreading along the waterfront with sloping ground under earthquake strike. It is of substantial importance, therefore, to evaluate the damage hazard and risk of the infrastructure located at areas vulnerable to liquefaction and lateral spreading in the basin. The data of boring log, ground water table, and cross section along each river (Tamsui River, Keelung River, and Xindian River) in Taipei Basin are collected first. Two possible earthquake scenarios with four different intensities according to aseismic design code (including design earthquake and maximum considered earthquake) and the rupture of Shanchiao Fault (including moment magnitude of 7.1 and 7.5) are considered. The spatial damage index of liquefaction is interpolated by the method of Sequential Gaussian simulation. The
    multilinear regression (MLR) model published by Youd et al.(2002) is used to evaluated the displacement of lateral spreading. And then, the approach suggested by UNDRO (1979) that combines the hazard and vulnerability is used to evaluate the risk of lateral spreading along the waterfront and the sites of bridge.
    It is shown that the risk of lateral spreading induced by the rupture of Shanchiao Fault is greater than those from design earthquake and maximum considered earthquake of aseismic design code. The influence of characteristic earthquake of Shanchiao Fault on the lateral spreading displacement is the most important, and thus it is need to be included for estimating the risk. In the scenario of rupture of Shanchiao Fault, the risks of lateral spreading adjacent to the sites near the bank of Tamsui River are the largest, with Xindian River being the smallest. Thus, if the sites of building, bridge, earthworks, and lifeline are located along those waterfronts with high risk, the countermeasures against soil liquefaction and lateral spreading must be made to avoid the associated damages when earthquake occurs.
