| 摘 要： | 采空区存在对高速公路的修建和运营安全产生严重影响,由于采空区具有隐伏性强、空间分布规律性差、冒落塌陷难以预测等特点,因此采空区治理具有一定的困难和不确定性,文章结合铜陵至汤口高速公路洪山小煤矿采空区的处治,阐述采用全充填压力注水泥粘土浆法治理采空区的设计要点,并提出工程质量检测标准和方法。

| Abstract: | Depressions due to mining have serious effect on construction and operation safety of expressway.The hollow lands are usually hidden and irregularly distributed,so the cave-ins are hard to predict,bringing difficulties and uncertainties in relevant treatment.With an example from handling the depressions due to small mines in Hongshan on the expressway from Tongling to Tangkou,this paper described the key design points for treatment of depressions by full filling of pressurized grout of cement and clay,and gave standard and method for inspection of the engineering quality. |
