摘要
以某典型桩锚支护结构基坑工程为例,介绍了锚索大孔径锚固体和大直径钢铰线的设计实践经验,根据场地特点,采用在地下室侧墙外设置出土坡道的方案,极大地方便基坑出土与后期地下室结构的材料运输。通过监测数据与理论计算对比,发现支护结构的变形与理论计算基本相符,说明方案实施效果良好,并分析了实测变形与理论计算差异的原因。该工程支护结构体系较为典型,可为类似工程提供参考。
Based on a typical deep excavation example using pile-anchor support,this article introduces the experience in the design and construction of anchor cable with large diameter anchorage body and steel strand.The reference engineering,due to the site characteristics,has adopted setting soil transport ramp at outer basement wall,which have greatly benefited the efficiency in transporting soil as well as the materials of basement structure that followed. Under comparison,the monitoring data and theoretical calculation meets well,which have proofed the method’s feasibility. The differences between the monitoring data and theoretical calculation have also been discussed in this article. The engineering listed in the essay is classical and can provide a reference for future similar projects.
