摘要
采用大型通用有限元计算分析软件ANSYS对某复合土钉墙支护基坑进行数值分析与研究.土体本构采用模量随深度变化修正后的Drucker-Prager模型,进行大量的数值计算与分析,研究开挖顺序和土钉长度等参数对坑壁水平位移、地表沉降和坑底隆起的影响,给出一些有益的结论,为今后工程中利用复合土钉墙进行基坑支护的设计与施工提供一定的参考.
The general finite element software ANSYS was utilized to analysis and study the foundation supported with composite soil nailing. The Drucker-Prager model modified with depth was adopted as the constitutive model. The effect of excavation order, nailing length and nailing obliquity to the horizontal displacement of foundation wall, surface sedimentation and rise of the foundation bottom was studied, and some helpful conclusion was given. The conclusion can be referred to the design and construction of foundation supported with composite soil nailing.
