摘　　要：实际工作中．应结合场地特点、地层分布、液化判圳资料的可靠性综合评价场地的液化等级。土液化的内闪取决于土的种类和状态．按勘探孔总数平均的液化指数划分场地的液化等级是不合理的。对规模较大的建筑群场地．宜采用“分区域取火值”的方法分区评价场地的液化势。Reliability evaluation of liquefaction grade site should be combined with the characteristics of the site. the stratigraphic distribution and liquefaction data in the practical engineering. The internal causes of soil liquefaction depends on the kind and state of soil, it is not reasonable to divide the site liquefaction grades according to the average liquefaction index of total exploration hole. For larger-scale building site, the method of selecting a large value subregionally should be used when the liquefaction potential of site is partitioned evaluation.
