地铁车站竖井施工的风险防范和应急措施综述

Summary of Risk Prevention and Emergency Measures for Shaft Construction of Subway Station

针对地铁车站竖井施工存在的风险,以沈阳地铁九号线皇姑屯站为例进行分析,并对主要施工风险作出相应的防范及应急措施。在竖井施工作业中主要存在对周边既有建筑物的环境风险以及竖井渗漏涌砂、失稳、坍塌等自身风险。竖井开挖施工过程中应提前作出相应的预防及应急措施进行风险防治,这对于有效加强施工质量及安全性具有非常重要的意义。

In view of the risks existing in the construction of subway station shafts, the Huanggutun Station of Shenyang Metro Line 9 is taken as an example for analysis, and corresponding prevention and emergency measures are taken for the main construction risks. In the shaft construction operation, there are mainly environmental risks to the existing buildings in the surrounding area, as well as the risks such as sand leakage, instability and collapse of the shaft. During the construction of shaft excavation, corresponding prevention and emergency measures should be taken in advance to prevent and control risks, which is of great significance for effectively strengthening construction quality and safety.
