PRE-STRESSED ANCHOR WIRE AND ANCHOR ARM COMBINATION USE IN DEEP FOUNDATION DITCH SUPPORTING

结合现有的基坑土钉支护设计规范,通过合理分析计算,介绍了贵阳某综合楼基坑支护中预应力锚索锚杆联合支护方案。实践证明,在岩体破碎和地下水资源较丰富的条件下,该类型支护方案能取得较好的效果。

Combining the Code for technique of building foundation pit engineering, the combination supporting scheme of prestressed anchor wire and anchor arm for a deep foundation ditch in Guiyang city is introduced.
