Composite Support Technique for Soilnailing Wall and Prestressed Anchor

摘要:

北京市深基坑工程中土钉墙支护技术应用比较广泛，对于边坡变形要求严格的基坑，采用土钉墙与预应力锚杆联合支护技术可有效控制变形，结合工程实例，介绍了该技术的设计思路及应用过程，说明了该技术的适用性，并就施工中遇到的问题进行分析，给出相应的处理措施。

Abstract:

The technique of soilnailing wall is widely applied in Beijing, and the composite support technique for soil-nailing wall and pre-stressed anchor can efficiently control the deformation. The design way and the applicability of this technique is illustrated with a field case, and analysis on some problems encountered during construction are made with the corresponding measures.
