摘　　要：对地基震陷震害及其影响因素进行了简单总结,整理分析了软土震陷的有关规范;结合工程实际钻孔对比讨论了软土震陷不同规范方法的优劣,提出了基于"两台阶的缩小范围量化"的软土震陷判别方法并进行了验证及工程应用。This paper summarizes the seismic damage of the ground earthquake settlement and its influencing fac- tors, collects and analyzes the codes relevant to seismic settlement of soft soil; Based on practical engineering drill- ing data, it analyzes and discusses the advantages and disadvamtages of the methods presented in different codes, proposes a ＂two-step narrow range quantization＂-based discrimination method of earthquake settlement of soft soil and verifies this methos in engineering applications.
