富水地层土压平衡盾构施工方法及管理措施

Construction Method and Management Measures of Soil Pressure Balance Shield in Water⁃Rich Formation

隧道开挖是隧道施工中常见的作业之一,其施工方法对隧道施工具有重要影响。在实际作业环节中,一些地区的地质较为特殊,含有较多的水分,一定程度上影响隧道施工的落实。土压平衡盾构施工方法作为专业的施工方式,通过先进的盾构机实现掘进作业,规避富水地层对施工产生的影响。本文从富水地层入手,探讨富水地层土压平衡盾构施工方法,分析其施工难点。在此基础上,对该施工方法进行详细分析,保证施工作业的落实。

Tunnel excavation is one of the common operations in tunnel construction,and its construction method has an important impact on tunnel construction,which needs to be paid attention to by relevant personnel.However,in the actual operation link,the geology of some areas is relatively special,containing more water,which affects the implementation of tunnel construction to some extent.As a professional construction method,the construction method of soil pressure balance shield works through the advanced shield machine to avoid the impact of water-rich formation on the construction.This paper starts with the water-rich stratum,discusses the shield construction method of the water-rich stratum,and analyzes the construction difficulties.On this basis,the construction method is analyzed to ensure the implementation of the operation.
