某深基坑支护体系方案选型设计分析

A System of Deep Foundation Pit Supporting Scheme Selection

通过对常州市轨道交通1号线一期工程控制中心基坑维护设计,结合该深基坑周围附属建筑物、构筑物,道路,地下车站、管线、管网等工程简况,以及该地区土层分布和水文地质等不同的环境条件,并结合钢筋混凝土桩、预应力锚杆、钢筋混凝土内部支撑、深基坑降水等基坑支护理论,利用天汉软件系统分析了多种支护方式的共同使用在深基坑支护体系中发挥的高效性、安全性、经济性,由此探讨此深基坑的支护方案。

Through the foundation pit maintenance design of of the control center of the Phase I project of the rail transit line 1of Changzhou City,combining with the deep foundation pit surrounding ancillary buildings,structures,roads,underground station,pipeline,pipeline engineering situation,and the region distribution and hydrogeologic different environmental conditions,and combining with the reinforced concrete pile,prestressed bolt,reinforced concrete internal support,deep foundation pit precipitation,such as foundation pit supporting theory,this paper uses the Tianhan software system to analyze efficiency,safety,and economy of the mutual-utilization of the multi-supporting methods in the deep foundation pit supporting system.The supporting scheme is to be discussed for deep foundation pit.
