本文基于不排水振动荷载下，振动能量与土的有效应力降低的关系方程；从地震 能量出发推导出一个判别地震荷载下饱和砂层液化势的半分析半经验的简便方法。为 验证该简便法的可靠性，针对几个已知的液化实例用该法进行了再判断。结果表明所建议的简便法是比较可靠、比较方便的一种方法。
Based on the relationship between the vibration energy and the effective stress reduction of soil under undrained vibration loads, this paper derives a semi-analytical and semi-empirical method for judging the liquefaction potential of saturated sand under seismic loading. In order to verify the reliability of this simple method, a re-judgement was made using this method against several known examples of liquefaction. The results show that the proposed simple method is a more reliable and more convenient method.
