摘要
某国有公路设计线路与某地下开采矿山相邻。为保证国道工程项目的顺利推进,对该公路与矿山开采的相互影响展开了研究和论证。以岩石力学、弹塑性力学、开采沉陷学等学科为理论依据,在参考相关研究报告及图纸资料等成果的基础上,详细分析了矿山老采空区稳定性及采空区引起岩层移动的影响范围。对采空区与公路的相互影响进行了数值模拟分析,然后对所获得的数据进行整理,对矿山已有空区及后续开采是否对公路工程造成安全影响做出评估。结果证明:矿山开采对公路不会造成危害,为该公路的建设提供了依据。
According to the design line,a state-owned highway is adjacent to an underground mine.In order to ensure the smooth promotion of the national highway project,the interaction between the road and the mining is studied and demonstrated.With the rock mechanics,elastic-plastic mechanics,subsidence and other disciplines as the theoretical basis,and based on the related research reports and drawings and other information,the old goaf stability and the influence of strata movement caused by the goaf are analyzed in detail. The numerical simulation analysis on the interaction between the mined out area and the highway is carried out,and the data obtained are collated to assess whether the mined out area and the subsequent mining have a safety impact on the highway engineering.The results show that the mining activity does not harm to the highway,which provides a basis for the construction of the highway.
