Abstract


Of Dan Shen Passenger Line DK53 200 ~ CK67 200 engineering geological conditions and DK63 300 ~ DK65 700 segment underlying goaf detailed investigation , in -depth research and analysis of the characteristics of the residual deformation after the end of the underground coal seam mining . In obtaining drilling data on the basis of analysis and expected duration of surface movement . Study the the residual subsidence coefficient of variation , and the application of residual subsidence coefficient applied probability integration method , based on the assumption of residual movement and deformation of the stratigraphic system , residual movement and deformation of railway construction and operation period do the expected . U.S. the ITASCA Advisory Group the FLAC3D procedures , application of explicit finite difference iterative step simulated residual movement and deformation of railway construction and operation period , and the results of probability integration method for mutual authentication . Dan Shen Passenger Line does not occur in the construction and operation period movement and deformation of the destructive conclusions are drawn on the basis of the probability integration method and numerical simulation .
