深基坑复合土钉墙受力性能的计算机模拟分析
Computer Simulation Analysis of Stress of Composite Soil Nail Wall in Deep Foundation Pit Excavation
摘要
Abstract
In order to reveal the laws of the stress of the composite soil nail wall of soil nails and cement⁃soil piles, a whole three⁃dimensional finite element calculation model was established on the basis of the numerical simulation method, which considered the spatial action of the foundation pit and overcome the deficiencies of two⁃dimensional plane model or a partial spatial one. The construction process of the composite soil nail wall was simulated and the axial forces of the soil nails were analyzed. The calculation results showed that: (1) The influence of the corner of the foun⁃dation pit was about 0.5 times of the depth of the excavation on axial forces of soil nails, (2) The location of maximal axial force of every row soil nails was 0.2~0.25 times of the length of soil nail from the excavation face,(3)Axial forces of the middle and lower soil nails were bigger.关键词
