软土夹层中土钉墙实例及设计施工探讨

Inquiry on soil-nailing wall examples in soft soil interlayer and design construction

通过对北京某软土夹层区域土钉墙支护施工技术以及支护效果的介绍,着重研究了该工程施工中土钉墙支护体系出现的突发情况以及相关解决方法,根据对比分析拟建场区的地层物理力学性质参数以及采用相关专业软件对不同部位的土钉墙支护体系重新进行理论计算分析,推测土钉墙支护体系突变的原因,并针对土钉墙支护体系突变根源对软土夹层区域中土钉墙支护体系的设计及施工提出相关建议,以确保软土夹层中土钉墙施工安全性。

Through introducing soil-nailing support technology in the soft soil interlayer region of Beijing and its support effect,the article mainly studies engineering construction emergent conditions and relevant solving methods in the soil nailing wall support system. According to comparative analysis,it simulate field stratum physical stress parameters and applies relevant professional software,carries out theoretical computation analysis for various soil nailing wall support system,and induces emergent soil nailing wall system causes. In light of emergent soil nailing wall support system sources,it puts forward corresponding design and construction suggestions for soil nailing wall support system in soft soil interlayer area,with a view to guarantee soil nailing wall construction safety in soft soil interlayer.
