摘要

土钉墙是用于基坑开挖和边坡稳定的一种挡土结构，将土钉与预应力锚杆结合形成复合土钉墙结构。根据土钉、预应力锚杆和土体的联合作用机理，提出钉-锚-土联合作用模型模拟复合土钉墙的支护锚固效应。将该力学模型用于指导设计一深大基坑支护工程，使基坑支护设计方案得到显著优化，确保了基坑开挖稳定和周边环境的安全，基坑支护获得圆满成功。

Abstract

The soil nailing walls is a kind of retaining structure to stabilize foundation pit and slope. Composite soil nailing walls is formed by combining soil nailing with prestressed anchor bar. According to the interactive mechanism of soil nailing

prestressed anchor bar and soil mass

a jointly interactive model is proposed to simulate supporting and anchoring effect of the composite soil nailing walls. The mechanical model is applied to a deep & large foundation pit which was designed by authors; and the supporting design scheme for the foundation pit has been effectively optimized. Stability of the foundation pit and safety of surrounding environment under excavation state have also been ensured. The supporting for foundation pit has achieved complete success.
