Abstract
With the development of the city,the effective use of city underground space is an effective way to solve the contradiction between development and land resources.Traffic problems brought by the development of city management has increasingly become the key issues to consider,therefore,the construction of large capacity of the city subway traffic has been the attention of managers.Because that Chongqing is a mountain city,and in the city expansion and the city formation,poor geological conditions,soil particle size,high water content and busy ground transportation,construction disturbance to the surrounding rock were caused,causing the deformation of metro tunnel,or even the occurrence of safety accidents and serious economic losses.The municipal traffic facilities construction in the complex environment becomes a difficult problem to many builders.Therefore,it is of great significance to study the construction technology of newly buried deep water rich tunnel in the city.The Bay Road to Chongqing metro line ten of the project on the mountain park tunnel through the most complex backfill section is took as the research object,and we analyze the tunnel construction technology from several aspects.The construction method adopted to solve the similar formation in the excavation construction problems,which has strong practical value and similar value study.关键词
