摘要
现沿用的按Ⅰ级破坏作为高速公路破坏的变形参考值造成了煤炭资源的浪费,本文通过数值模拟手段研究采空区高速公路路基的破坏,指出高速公路路基能承受地表水平变形Ⅱ级变形(即水平变形≤4mm/m),据此进行采空区处治理设计与煤柱留设计算,能够节约一定的煤炭资源量,节约建设成本,从而为相关工程设计与施工提供理论指导。
Deformation value of expressway influenced by mining coal which is selected as Ⅰlevel failure in current standard will result in coal resource waste. By numerical simulation, this paper indicated that roadbed of expressway could bear surface Ⅱ level horizontal deformation （≤4mrn/m） . On the basis of this, gob treatment and coal-pillar design was made to save some coal resource and con- struction cost, and theoretical reference could be provided for similar engineering design and construction.
