地下停车场深基坑支护结构设计及施工监测研究

Design and Construction Monitoring of Deep Foundation Pit Support Structure for Underground Parking Lot

针对当前深基坑支护建设工程工期长、效率低的问题,提出了采用三轴搅拌桩施工工艺来进行支护桩的建造,同时,针对深基坑支护建设工程进行了监测方案的研究。通过提出方法建造的支护桩整体稳定性系数为2.375,大于相关规范规定的1.35。

In view of the problems of long duration and low efficiency of the current deep foundation pit supporting construction project,the three-axis mixing pile construction technology is put forward to build the supporting pile,and the monitoring scheme is studied for the deep foundation pit supporting construction project.The overall stability coefficient of the supporting pile constructed by the proposed method is 2.375,which is greater than 1.35 stipulated by the relevant standards.
