摘要
以南宁地铁某区间穿越湖泊和河流为研究对象,运用理论分析、现场监测和数值模拟相结合的手段进行研究,利用数值模拟软件模拟水位变化影响地铁隧道变形过程,分析了不同覆土深度、不同水位变化对盾构隧道变形的影响大小,通过与实测数据的对比分析总结了地表水位变化对运营地铁隧道变形影响的规律,为类似项目分析提供参考依据。
Metro interval through the lakes and rivers in nanning as the research object,using the combination of theoretical analysis,field monitoring and numerical simulation method are studied,using numerical simulation software to simulate water level changes affect the subway tunnel deformation process,analyzes the different turns the soil depth,the influence of different water level change on shield tunnel deformation size.The law of the influence of surface water level change on the deformation of subway tunnel in operation is summarized by comparing with the measured data,which provides a reference for the analysis of similar projects.
