摘要

评定地基土液化可能性是抗震勘察设计中的一个重大课题,通过对比《建筑抗震设计规范》推荐判别方法与美国Seed判别法,推导出新的判别方法,该法具有判别准确、理论合理、计算简便、与工程实际相结合等优点,是一种值得推广的判别方法。
Sand liquefaction evaluation plays important role in seismic investigation and design of building.Based on the contrast between the most frequent methods in the evaluation of liquefaction,such as the method recommended in code for seismic design of building(GB50011-2001) and Seed method,a new method for evaluation liquefaction is deduced.The method possesses many preferred qualities,such as its accurate result,the reasonable and simple process of calculation and the close relation with engineering.Extensive application is advisable.
