Study On The Construction Organization And Design Of Tunnel Foundation Pit Engineering Of Xi’an City The South Gate And Huancheng South Road

In this paper, based on the construction of the foundation pit under the south gate andhuancheng south road, the supporting,precipitation, monitoring of foundation pit, and theprotection of underground pipeline, traffic guidance, etc are studied in detail during theexcavation of foundation pit,for solving problems that construction diffeculty is large as wellas the influence on the surrounding environment and traffic.Considering the engineering geology, the water level geological situation, and undergroundpipeline, and traffic factors, two sets of foundation pit construction scheme are provided.through comparive analysis to the schemes, a reasonable construction scheme of foundationpit is to determine, that is a construction plan to bored and supporting within the support, anda detailed analysis of the project about is made.The hydrogeology and surrounding environment in engineering area are comprehensivelyanalysis, a set of reasonable construction scheme of foundation pit pre constructionorganization cipitation is put forward through calculation.In foundation pit construction process, the surface subsidence, horizontal displacement,ground water level and supporting axial force are monitored. with the measured results, theproblems existing in the process of theoretical analysis are covered, and the monitoring resultsare feedback to the design and guide the construction, meanwhile, it is a method to verify therationality of the design and construction.Considering the influence of the area traffic conditions and underground pipeline, thereasonable traffic organization measures and the underground pipeline protection schemerespectively are put forward, to ensure the safety, rationality and validity of foundation pitengineering construction.
