城市轨道交通工程地下水风险综合防控措施研究

STUDY ON COMPREHENSIVE PREVENTION AND CONTROL MEASURES OF GROUNDWATER RISK IN URBAN RAIL TRANSIT PROJECT

为对城市轨道地下水风险进行综合防控,借助GMS与MIDAS/GTS数值模拟软件形成城市轨道交通地下水综合模拟分析技术,弥补地下水控制工程勘测阶段分析不足、设计阶段计算方法单一的问题;通过对实际工程的研究分析与问卷调查,总结了地下水控制工程及总体施工的安全风险问题及应对措施,从而形成了综合防控措施体系。并根据施工经验总结成果,对研究区进行地下水风险综合防控分析,最终形成综合防控措施建议。

In order to comprehensively prevent and control the risk of groundwater in urban rail transit, this study forms a comprehensive simulation and analysis technology of groundwater in urban rail transit with the help of GMS and MIDAS/GTS numerical simulation software, which makes up for the lack of analysis in the survey stage of groundwater control engineering and the single calculation method in the design stage. Through the research, analysis and questionnaire survey of the actual project, the safety risk problems and countermeasures of groundwater control project and overall construction are summarized, so as to form a comprehensive prevention and control measure system.According to the construction experience and summary results, the comprehensive prevention and control analysis of groundwater risk in the study area is carried out, and finally the comprehensive prevention and control measures and suggestions are formed.
