井采诱使加筋板处治拓宽路基路面变形破坏模型试验

Treatment of stiffened plate wells to induce deformation and failure model Pavement widening Test

针对高速公路穿越我国矿产资源丰富地区,井工开采活动情况,利用比例模拟方法开展模型试验,研究跨越采空区公路通车运营后重交通情况下路基路面的变形破坏规律,特别揭示了井采诱使加筋板处治拓宽路基路面变形破坏。采用加筋板处治方案时,煤层开采会造成路面的沉降,但是由于加筋板的作用,路面沉降量得到协调控制,差异沉降很小,不会对路面结构造成大的危害。

For the highway through the region of China rich in mineral resources, underground mining activities, the proportion of simulations using model tests carried out to study the highways across the gob after operation under heavy traffic conditions subgrade deformation law, in particular, reveals the lure Wells to broaden the Pavement Treatment stiffened plate deformation. Treatment programs using stiff- ened plate, when the coal seam can cause surface subsidence, but because of the role of stiffened plate, the coordination of control surface subsidence, differential settlement is small, not on the pavement cau- sing great harm.
