高速公路下伏采空区勘察与评价方法探讨

Damage Estimation Method of Multilayer Incline Mine Goaf under Expressway

高速公路穿越煤矿采空区的问题是近年来公路建设中经常遇到的技术难题 ,本文以京福国道主干线徐州绕城公路东段为工程依托 ,对高速公路下伏多层采空塌陷区的勘察方法和稳定性评价方法进行了研究 ,提出了高速公路下伏多层采空区的综合预计评价方法 ,对于相似情况下的工程具有重要的参考价值。

Thedifficult technical problem appears that expresswayis built on mine goaf in recent years.East section cirˉcum-Xuzhouof National highway from Beijing to Fuzhou is adopted as a example,stabilization estimation method of mine goaf umder expressway are studied,the compositive prediction dnd estimation method are proposed.All these reˉsearch have important reference value to similar engineering.
