近年来,随着我国城市经济的不断发展,为了缓解城市交通压力,各大城市均开始修建地铁。而地铁车站施工中仍存在一些难点,尤其是地铁车站深基坑开挖过程中,通常会遇到各种难题,都会为后续的地铁施工埋下一些安全隐患。文章结合笔者的实际工作经验和工程实例,主要针对某地铁车站深基坑土方开挖施工技术要点进行了分析与研究,主要从施工方案的选择、施工流程、施工前准备和施工技术等方面进行了论述,旨在为大家提供参考。
In recent years, with the continuous development of the urban economy in our country, all major cities have begun to construct the subway in order to ease the pressure of urban traffic. However, there are still some difficulties in the construction of metro stations. In particular, during the excavation of deep foundation pits of metro stations, various difficulties are usually encountered and some potential safety problems will be laid for subsequent metro construction. Based on the author’s actual work experience and engineering examples, the article mainly analyzes and studies the technical points of earth excavation for deep foundation pit of a metro station, mainly from the aspects of construction scheme selection, construction process, preparation before construction and construction technology The discussion, aims to provide a reference for everyone.
