| 摘 要： | 西合高速公路采空区位于丹江河谷二级阶地区,主要是人工在基岩顶板上的卵石中挖沙金废弃的矿洞,埋深较浅,严重影响高速公路的建设和运营。在分析其形成及分布特点的基础上,结合工程物探资料,采用结构力学方法、极限平衡法对采空区进行了稳定性评价,并针对西合高速公路下伏采空区的具体特点,提出了开挖回填、钻孔灌浆及在路基中铺设土工格栅的治理方案,可为同类型采空区的治理提供参考。

| Abstract: | Xihe expressway's gob is located in the second terrace of Danjiang. It was formed because the sand-gold ore holes left behind in the hanging wall of the bedrock and at its depth were shallower, and the construction and operation of Xihe expressway was badly affected. Based on the analysis of its formation, distribution, in combination with the physical prospecting data, the stability of gob was evaluated by way of structural mechanics. According to practical situation, the treatment programs such as excavation,backfill,drilled inject and civil grid were put forward, thus providing a good reference for similar gobs. |
