Construction Risk Controlling And Monitoring Of Changchun Children’s Park Subway Station

The subway station construction will inevitably have adverse impact on the infrastructure in the nearby area because of many construction steps,complex force conversion and frequent disturbance of strata.During the construction process,if we can determine the building deformation due to excavation,and the construction steps causing the maximum disturbance of strata subsidence in advance.At the same time,giving solutions and measures of enhance.In this way,we can not only ensuring the safe and efficient construction,but also minimizing the impact of cavern construction on the surrounding buildings,roads and pipelines.Meanwhile,improving the economic and social benefits of station construction have great practical significance.This paper study deeply of the following content which based on the Changchun Metro Children’s Park Station project.1)The engineering background,surrounding environment and hydrogeological conditions of Children’s Park station of Changchun metro are analyzed in detail,and the risk factors affecting the station construction are studied.2)The construction of Shanghai Pudong Development Bank,the system of Metro cavern excavation analysis of a wide range of Shanghai Pudong Development Bank influence and differential settlement of law surrounding the excavation of the subway,according to different excavation sequence optimization analysis,find out the most safe,economic,efficient and the excavation scheme,the largest source of risk of Shanghai Pudong Development Bank No.2 shaft ingate broken study on Optimization of hole technology.3)Through the study on Station shallow key technology of bad geological body construction,establish a set of perfect,maneuverability,adverse geological treatment measures comprehensively.The different processing methods were summed up according to the unfavorable geological body.
