复合土钉墙在软弱土层支护中的应用

Application of Composite Soil-nailing Wall Support in Soft Ground Excavation

由于银海大厦基坑施工中软土变形较大 ,根据深基坑工程地质水文地质条件 ,优选了旋喷桩与土钉墙构筑复合土钉墙的方案进行施工 ,避免了水土流失 ,减少了基坑变形 ,支护稳定 ,取得了良好的效果。

The use of soil-nailing wall support in soft ground in Yinhai mansion caused some deformation and difficulty in construction. A preferential program is selected by using high-pressure jetting pile and soil-nailing to establish composite soil-nailing wall, which avoids water-earth loss, decrease deformation and improve the stability of support.
