１　前　　言*深基坑有限元分析方法可以较全面地考虑多种复杂因素的影响，因而越来越受到重视。但目前有限单元法计算精度太低，致使该方法仍处在辅助设计水平上。其原因是多方面的［１］，其中固结及土－结构相互作用的模拟过于粗糙是两个不容忽视的因素。前人已对这２个因素 1 Foreword* The deep foundation pit finite element analysis method can more comprehensively consider the influence of various complex factors and is therefore receiving increasing attention. However, at present, the accuracy of finite element method is too low, so the method is still at the level of auxiliary design. The reasons for this are many aspects [1], in which consolidation and soil-structure interaction simulation are too rough to be two factors that cannot be ignored. The predecessors already have these two factors
