桩—锚联合在深基坑支护中的应用和优化设计

The application and optimum design of pile-anchor joint supporting system in deep excavation work

以郑州某小区基坑支护工程为实例,介绍了桩—锚联合在深基坑支护中的应用及预应力锚索、套管跟进内循环钻孔工艺技术的使用,经过精心设计与严格施工取得了良好的经济和技术效果,为同类深基坑支护工程提供了借鉴作用。

Taking one excavate support engineering in Zhengzhou as example the application of pile-anchor joint supporting system is introduced as well as construction technology of prestressed anchoring cable and sleeve＇s following up drilling, Elaborate design and strict construction acquire good economic and technical effects, which provide good references for similar works.
