地铁上盖深基坑施工相关问题探讨

广州地铁现有1号线、2号线、3号线、4号线、5号线、8号线、广佛线及APM线,广州地铁总里程236km(包括广佛线广州段)。而广州地铁的远期规划长度是600km。未来很多大型建筑会与地铁无缝连接或在地铁上盖建筑楼宇,地铁上盖深基坑是必然遇到的施工趋势。分析地铁上盖深基坑施工,并通过一个工程实例进行相关要点控制。

Research on Deep-foundation Pit Construction of Metro-superstructure

Ouangzhou metro system now has Line 1, 2, 3, 4, 5, 8 and Guangfo Line, also one APM Line. Total mileage of the metro system is 236km （Guangzhou section in Guangfo Line is included）. The prospective planning of Guangzhou metro mileage will be up to 600km. In the future, plenty of massive buildings will be tightly connected to the metro station. Or, more and more metro-superstructures are rising up. The deep-foundation evacuation will become the main method in constructing the superstructure upon the subway. This article is to describe and analyze the deep-fuundation pit construction and, together with a project case, to present the main control issues.
