【摘要】 为了进一步研究土钉和土体的协同工作机理 ,以杭州孔雀大厦土钉墙支护为实例 ,依据土钉抗拔反演分析参数 ,应用有限元方法模拟基坑开挖和土钉支护的施工过程 ,分析了土钉内力和土体位移在动态施工过程中的变化规律 ,同时获得了注浆加固后土体的力学指标 ,供土钉墙支护结构设计和施工参考 .更多还原

【Abstract】 In order to study the mechanism of soil-soil nail interaction, FEM was applied to simulate the process of excavation and soil nail support, based on the back analysis parameter of soil nail pulling test with the example of soil nail support applied in Kongque Building. Soil nail internal forces and soil displacements are analyzed with construction process, at the same time the mechanics parameters of soil grouting reinforced, which provide reference for the design and construction of soil nail wall.更多还原
