摘　　要：研究了将深基坑桩墙支护结构视为弹性地基梁的数值分析方法 ,推导了采用“混合结构力学法”求解该问题的基本力学方程 ,提出采用“荷载增量法”模拟深基坑开挖施工的全过程 ,简要介绍了笔者多年来开发应用的深基坑桩墙支护结构设计软件系统PW’98。The numerical analysis method of the deep fundation pit pile/wall retaining structure which is regarded as beam on elastic fundation is studied,and accordingly,the fundamental mechanical equations with composite structure mechanics method are derived.The writer also explores the possibility of simulating the full process of deep foundation pit excavation with load increment method.A CAD software PW'98 for deep foundation pit pile/wall retaining structure design developed by the writer over years is introduced with an example.
