由于影响砂土地震液化的不确定因素很多,现有预测方法常常得不到满意的结果。本文探索了一种新的途径,即根据已有的现场砂土地震液化资料,用优选法对各影响因素进行优选,然后用优选结果进行预报。用本方法对14个现场实例进行预报,正确率达93%,表明所建议的方法是有效而可行的。 Due to the large number of uncertainties affecting the liquefaction of sand and soil, the existing prediction methods often fail to obtain satisfactory results. This article explores a new approach, that is, based on the existing site liquefaction data of sand and soil, optimize the influencing factors using the optimal method, and then use the preferred results to forecast. This method was used to forecast 14 site instances with a correct rate of 93%, indicating that the proposed method is effective and feasible.
