摘要
本文根据标准贯入试验、静力触探试验和便携式动力触探试验的测试数据,采用了多种计算方法进行了砂土的液化判别,其中标准贯入试验法与Robertson法、Lepetit法所得到的结论基本一致,上部地基土层为非液化土层,而采用静力触探试验法所计算出来的结果偏于安全,这与锥尖阻力基准值的取值大小有关。本文在介绍最新液化计算方法的同时,通过多种试验手段和不同液化判别方法的对比分析,旨在探讨综合判别砂土液化的可行性。
The paper adopts different liquefaction methods and calculates the liquefaction value against experiment results acquired by field-test, including SFF, CFF and PANDA. The SFF method has the same conclusion with the Robertson and the Lepetit methods. The top soil is non-liquefaction soil, however, the result derived from the CPF method is safer, it depends on the benchmark data. By introducing some new liquefaction methods, different experimental means and calculation is compared and the feasibility of sand liquefaction is analyzed in this paper.
