摘要
通过对采空区引起地表沉陷破坏类型、分布规律及公路结构分析 ,综述了采空区对高等级公路的危害程度及其主要因素。给出各类采空区对公路危害程度的评价方法与公路下伏采空区的处治防护原则。指出采用合适的开采方法减小地表沉陷破坏、改变公路路基、路面结构及材料、提高公路抗变形能力是保护矿区公路 ,实现安全、经济建路的有效途径。
By analyzing the destructiveness type of surface subsidence caused by gob,the law of distribution and the structure of road,the endanger extent and the main affection factors of high class highway caused by gob is discussed. The endanger level estimation method of various gobs to road and the management and protection principle of gob under road are given. The effective way that protect mine road and achieve safe and economic building road are using suitable mining method to reduce destructiveness of surface subsidence,changing roadbed of road,altering structure and material of road surface,increasing the resistance to decrease deformation of road.
