Abstract


Currently, the largest city rail transit network planning and construction , the new line through the existing railway line station is the inevitable question , when the construction of its short-range interaction is very complex , and how to minimize the impact , both to ensure that the new the smooth construction of the structure , but also to ensure the safety of the existing lines , the normal operation , seeking a safe , reasonable and economical construction methods has become an important issue . Since the construction of the railway network of China 's major cities is not perfect . It can be predicted that the new repair line station with the existing lines the station interchange of engineering , will continue to occur in the future the ground railway network construction process . There is no doubt that the impact of the construction of the new line stations across the existing railway line station , as well as short-range construction impact in-depth study is very useful and necessary . Sports West Road , Guangzhou Metro Station , calculated by the numerical simulation of a new metro line station beneath the existing subway station construction process , analysis beneath the station on the existing station , the following main research content : ( 1 ) calculated using the common mode of action of the stratigraphy and structure of the elastic-plastic three-dimensional finite element , consider the effect of the construction process of the space , construction mechanics analysis by finite element software Ansys , in the construction process is to get a new pit and existing station structure deformed by the force of law , as well as surface subsidence caused by construction . ( 2 ) study the construction of surface subsidence in the existing line operators , the selection of the optimal mechanical parameters and supporting structure parameters . Reasonable excavation , reduce excavation footage advance support , reduce the disturbance of blasting construction on the surrounding rock , and at the same time to ensure the safe operation of the existing station , the successful completion of the construction of new repair line station . ( 3) In order to facilitate the monitoring of the cut tunnel measurement , evaluation of metro tunnel construction on the safety of existing structures and methods , and reference to past experience in construction , surface subsidence control value calculated as a construction monitoring measurement indicators. Finally, the main conclusions of the deficiencies and recommendations of the study are discussed and put forward their own views and opinions .
