文章通过某地下洞库工程衬砌施工中支撑体系的选定,介绍液压台车及满堂支架两种不同的衬砌支撑体系,并通过比较,分析两种支撑体系在工期、施工成本、安全管控、材料再利用等方面的区别,找出工期、施工成本的临界点,提出合理、经济的选择支撑体系的方法,为类似工程施工提供一定参考。 In this paper, two kinds of lining support systems of hydraulic trolley and full support are introduced through the selection of supporting system in the lining construction of a underground tunnel project. By comparison, the two support systems are analyzed in terms of construction period, construction cost, safety control, Reuse and other aspects of the difference between the construction period to find the critical point of the cost of construction, put forward a reasonable and economical way to choose a support system for similar projects to provide some reference.
