采空区高速公路路基变形失稳的影响因素

Influencing Factors of Expressway Subgrde Deformation and Instability in Stope Area

矿体开采后会留下采空区。许多公路、铁路需要建在采空区之上或穿越这些采空区,面临因采空区塌陷所导致的路基失稳与破坏问题。了解采空区影响高速公路路基变形失稳的因素,对于有效避免此类病害发生具有重要指导意义。

Stope area will be left when the exploitation of mineral products is finished. However, the highway and railway infrastructure is often necessary to be built on or pass through such areas, which will face the prob- lems as subgrade instability or destruction caused by collapse of the stope area. It is very instructive for avoiding such diseases to get clear of the relevant influencing factors.
