摘要
根据地下开采引起的地表破坏现象,借鉴建筑物下、水体下、铁路下采煤,结合高等级公路自身属于带状建筑物的特点,分别讨论了地下开采引起的地表下沉、倾斜、曲率、水平移动和水平变形对高等级公路的破坏现象。地下煤炭被采出并达到一定规模后将引起采空区上覆岩层冒落破坏,继续开采,破坏现象将影响到地表,引起地表移动变形,导致地表建筑物、构筑物受到不同程度的破坏。对于高等级公路,地下开采影响到路基路面后,将使高等级公路产生路面移动盆地、路面台阶和裂缝、路面塌陷坑和塌陷槽、路基高路堤沉陷以及边坡坍方等破坏现象。
According to the surface damage caused by underground mining,with the reference of the coal mining under the buildings,water and railway,and combining with the characteristics of band structure of high-grade highway,the paper discussed the damage of surface subsidence,inclination,curvature,horizontal displacement and horizontal deformation on high-grade highway caused by underground mining.It will result in caving of the upper rock layer covering when underground coal resources are mined out to be a certain degree.If mining continued,the damage will lead to the surface and ground deformation,and badly affect the buildings and structures on the surface.For high-grade highway,underground mining will produce failures of moving pavement basin and pavement steps,collapse road pit and tank,settlement of high road embankment,landslides and other damages.
