摘　　要：针对在老采空区上方建设高速公路的问题,提出了一种新的地基稳定性评价方法,将由开采引起的导水裂缝带发育高度与地基载荷的传递深度等因素相结合,作为路基稳定性的标准,并对评价出的结果给出了一定的治理方法。为实际应用提供了参考。Aiming at the problems of construction highway above goaf, a new method of evaluation for roadbed stability, which integrates the main affecting factor as height of water flowing fractured zone caused by mining with transferred depth of foundation load and other loads is proposed in this paper and put it as the standard of roadbed stability. Then the paper gives some treatments for the result of evaluation which can be used as the reference for practice.
