地铁车站工程施工中围护结构是重要的一个环节。本文以某车站为例对柱列式灌注桩内撑式支护结构型式的设计计算、土方开挖、支撑架设、体系转换、信息化监测等进行了研究与应用介绍。 The construction of metro station construction envelope is an important part. In this paper, a station is taken as an example to introduce and research the design and calculation of the internal support structure type of column-column cast-in-place piles, earth excavation, support and erection, system conversion and information monitoring.
