摘要
泵房坐落于杂填土,周边大部分开挖易造成孤立,因此选择采用挖孔桩、微型桩结合对穿锚杆进行支护加固。文章主要介绍了支护设计方案,特别阐述了在实施过程中遇到的问题和处理方法,针对该条件下的支护方法进行了深入的分析探讨,为深基坑支护技术的发展提供了宝贵的实践经验。
Peripheral excavate in the miscellaneous fill can be easily create the isolation of the pumping station.Combining of dug piles and micro piles along with the horizontal anchors is a good way to reinforce the supporting system.This paper introduces the supporting design,elaborates the problems encountered in the process and solutions,analyses and discusses the supporting method under such situation,and provides a valuable practical experience for the development of deep foundation pit supporting technology.
