摘要
将土钉锚喷技术应用到重力式挡墙的结构施工中,形成双向土钉锚喷重力挡土墙。以北京某奥运窒外地下雨水收集池基坑支护工程为例,对它的设计原理、稳定性计算以及使用范围进行了详细说明,特别是对该方法在挡土墙加固方面的设计及施工方法进行了全面阐述。工程实践证明,该方法具有安全性大,施工效率高,费用低的特点。
The paper describes soil nailing bolting and shotcrete technology used on gravity retaining wall structure construction, thus two-way soil nailing bolted and shotcrete gravity retaining wall formed. To take foundation pit support engineering of a Beijing Olympic outdoor underground rainwater gathering tank as an example, explained its design philosophy, stability estimation and limit for the use in detail, especially expounded the method in retaining wall reinforcing design and construction in the round. The engineering practice has demonstrated that, the method has characteristics of reliable security, higher efficiency of construction and lower cost.
