| Abstract: | According to the regularity of the ground deformations of the mining subsidence area, a rational calculating model of numerical simulation was set up. Additive stress and deformation of the bridge structure caused by underground mining was studied. The bridge structure and foundation in the process sinking was also analyzed. A bridge reinforcement project was presented. By it the bridge can be used safely and reliably in the deformation of the earth surface of the mining subsidence. |
