Impact Analysis and Protection Measures of Municipal Pipeline Crossing Existing Subway Stations in Short Distance
When a new municipal pipeline straddles an existing subway station,the adjacent construction will cause the settlement of the existing subway station structure and affect the structure and operation safety of the existing subway station.Taking the impact of rainwater culvert in Dingli Street(Wenzhi Road-Ling-dong Road)in Zhengzhou on the parking line structure of rail transit planning Line 16 as an example,this paper uses qualitative and quantitative analysis and numerical simulation methods to analyze the adverse im-pact of existing rail transit construction near the new rainwater culvert,and proposes relevant measures to en-sure operation safety according to the relevant protection regulations of Zhengzhou rail transit.On the premise of ensuring the safety of rail transit structure and operation,the construction of this project is suc-cessfully completed,and the relevant experience can provide a reliable reference for the design and construc-tion of existing subway structures adjacent to and across similar municipal projects.
