当前由于土地资源限制等多种因素的制约,地下工程之间的距离越来越小,基坑支护的设计与施工变得异常复杂。对于复杂的地下空间开发,需要在规划确定之后即进行有效的施工筹划,以确定其地下支护空间、支护方法、施工方法及施工时序等问题。本文以武汉王家墩核心区地下交通的施工筹划为例,提出了复杂地下工程施工筹划的基本原则,分析了地下工程分属于多个业主时的施工筹划方法。
At present, due to restrictions on land resources and other factors, the distance between underground works is getting smaller and smaller, and the design and construction of foundation pit support are extremely complicated. For the development of complex underground space, it is necessary to plan effective construction after the planning is confirmed so as to determine the subsurface support space, supporting methods, construction methods and construction timing. Taking the construction planning of the underground traffic in the core area of Wangjiadun in Wuhan as an example, this paper puts forward the basic principles of the construction planning of complex underground works and analyzes the construction planning methods when the underground works belong to multiple owners.
