摘要
根据煤矿采动区地表沉陷变形规律,建立合理的数值计算模型,研究地下开采引起的地表移动变形对原设计的桥体结构和地基产生的附加内力和附加变形规律,提出了有效地加固治理方案,确保在采动引起的地表不均匀、大幅度沉陷过程中桥体的安全可靠和正常使用.
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.
