摘要
山区高速公路穿越煤系地层路段,不可避免经过大型复杂煤矿形成的采空区,根据采空区的规模及开采模式、采空率、地质结构等因素,对采空区的稳定性进行评价,结合高速公路在本路段的通过形式,对A,B 2个方案进行比选。并结合采空区的治理难度、构造物的形式,得出A方案较为合理的结论。
Epress way pass through mined-out area,as it pass through Coal-bearing strata. Analysising the stability of mined-out area based on Scale. mining mode. mined rate, geological structure, comparing toe routes,got that plan A is better than B. Provided reference for Similar problems in the future by analysis of Songhe mined-out area.
