Abstract


With the the strong urban underground space development and utilization , pit the impact of construction on the surrounding environment is becoming increasingly prominent. In recent years , the foundation pit construction - induced peripheral surface subsidence , road collapse , rupture of underground pipes , cracks in the bridge , buildings heavily skewed and other accidents are common ; resulting traffic jams , loss of life and property as well as the adverse social influence . Therefore, the induced environmental impact of underground space in a timely manner and control examples of typical engineering analysis , research has a certain practical significance for regional and project support technology . Paper relies on the \to remove the impact of construction on the strata disturbance , according to the foundation pit deformation mode , more than the rate of deformation of the construction period and the monitoring point correlation to predict the deformation process of the project under a reasonable construction monitoring points curve . (2) application of numerical analysis the software FLAC 3D < / sup > of the project to simulate the deformation curve analysis of the out - patient ward building and continuous Qiangding monitoring points , compared with the predicted curve obtained in the formation conditions parameters of analog excavation . (3) - support combined supporting pile and hospital wards floor underground garage numerical simulation to predict near building subsidence change course and surface deformation law for the construction reference . In this paper, the area of urban underground space construction support technology , the new urban underground space design , construction , operation and use of match with the development of a harmonious society . The demonstration and operability , in the region of urban underground space development and construction to provide a reference .
