某超高层建筑深基坑支护承压水下锚杆施工技术

Construction Technology for Deep Foundation Excavation Supporting with Anchor Under Confined Water of a High-rise Building

结合某超高层工程,针对工程的水文地质条件及周边环境,采用一种全新的锚杆施工工艺,在承压水下实现应用锚杆进行基坑支护的构想。从工艺试验设计、基本试验分析、施工过程控制及验收试验验证等方面详细介绍了该技术。实践结果表明,该技术取得了良好的效果。

Based on engineering practice, according to the geology and hydrology condition and surrounding environment, the authors are trying to demonstrate the concept that anchors can be used for foundation excavation supporting under confined water adopting a newly created anchor construction technique. This technique is introduced with detail from the aspects of process test design, basic test analysis, construction process control and acceptance test verification. Practice results show that this technology obtains good effect.
