摘要
以包神铁路下伏采空区为例,开展采空区覆岩稳定性模拟试验研究。通过对采空区破坏状态、位置、采空区围岩的破坏过程、机理和冒落规律进行分析,总结出铁路路基下伏煤层采空区的分布特征,为有效治理采空区提供依据,对于确保铁路运输安全具有一定的参考价值。
Taking the goal under the Baoshen railway as the research example, simulation test is conducted on the stability of surrounding strata of the goal under railway. The collapse state, location of the goal, the destruction process, mechanism and caving rule of the surrounding strata of the goal are analyzed in depth, therefore,the distribution characteristics of the goal of the underlying foal seams under the railway subgrade is summarized so as to provide the basis for effective governance goal. Besides that, the research results in this paper can also has the certain value for ensuring the safety of railway transportation.
