| Abstract: | To study the displacement and deformation laws of bridge in mining area,we predicted the ground settlement using the probability integral method and obtained the ground displacement based on observation data.According to the predicted data,we adopted the method of grouting into bed-separation in overburden to control the ground settlement based on geological conditions and observation data in Daping mine.Then we analyzed the deformation laws of overburden,dynamic development of bed separation,and the mechan... |
