摘要
对于北京地区既需要施工降水,又需要进行边坡支护的深基坑,常用的方案是采用管井或止水帷幕控制地下水、土钉墙或桩锚支护结构进行边坡支护。本文介绍了一种全新的施工方案,即创新运用SMW工法桩结合预应力锚杆在满足边坡支护的要求下同时满足基坑边坡止水的作用。工程实践表明,该方法大大降低了成本,取得了较好的效果。
For deep foundation excavations in Beijing,that need both dewatering and slope supports,a general scheme is to use tube well or waterproof curtain to control the underwater water and use soil nailing wall or pile-anchor structure for slope support.This paper introduces a new construction technology,which innovatively uses SMW method in combination with prestressed anchor to provide slope support,while satisfying the requirement of water stopping.Engineering practice shows that this technology can reduce cost and obtain good effect.
