The seismically induced soil liquefaction has become one of the very important issues in the earthquake engineering designs and disaster prevention and mitigation since the 1999 Chi-Chi earthquake which caused extensive soil liquefaction damage in the middle part of Taiwan. In the evaluation and design against soil liquefaction, it is imperative to consider the specific characteristics of the geologic conditions, seismicity, and the soils, especially the very high fines content, in the probable liquefaction areas in Taiwan. This paper discusses, specifically relevant to Taiwan, the present state of knowledge and practices, major problems, and future developments in the areas of (1) liquefaction behavior of soils with a high fines content; (2) soil liquefaction evaluation methods; and (3) engineering designs against soil liquefaction.
