| 摘 要： | 在采用弹性理论结合有限元法建立力学计算模型的基础上,将开挖面以上支护桩(墙)取为梁单元,开挖面以下取为弹性地基梁单元,将锚杆模拟为弹簧,考虑土体对支护结构的摩擦效应和土压力形成的动态过程,采用弹性杆系有限元法编制有限元程序,并结合工程实例分析了桩(墙)锚杆支护结构的位移和内力变化情况,为深基坑桩(墙)锚杆支护结构的设计理论和方法提供了参考依据.

| Abstract: | Questions of retaining systems of deep foundation pit,such as design theory and construction technology which are in existence at home and abroad,were studied design and theory of optimization of retaining systems of pile(wall)-anchor were investigated.Corresponding analysis of finite element law on this basis was made,some opinions about information construction was given. |
