摘　　要：高速公路的选线主要从总体经济社会效益考虑,特别是在山区选线难度大,工程造价高,往往不能顾及局部地段的特殊情况。重庆綦万高速公路(綦江-万盛)就从南桐矿业公司南桐煤矿北翼煤田上通过,压占该矿大量煤炭资源。因此,开展高速公路下采煤,运用采煤后上覆岩层移动变形规律的科研成果,对高速公路的下沉、倾斜、曲率、水平移动和水平变形等采动损害做出定性和定量的研究与分析,对其安全性做出评估和判断,并提出安全对策,就成"三下"(建筑物下、水体下、铁路下)采煤研究者的新课题。针对山区高速公路的特点,以綦万高速公路为例,系统研究了地下采煤对高速公路的影响,并进行了采动损害评估,对运营中的綦万高速公路下采煤做了初步探讨,提出了应采取的安全技术措施。The expressway route selection should mainly consider the overall economic and social benefits and especially in case of mountainous areas, it can involve great difficulty and high engineering cost and often has to neglect the special conditions for some local sections. Chongqing Qijiang-Wansheng Expressway passes above the coalfield on the north wing of Nantong Coal Mine of Nantong Mining Company and covers and occupies a large amount of coal resource of the mine. Therefore, mining the coal under the expressway, making quantitative and qualitative research and analysis of the mining-caused damages such as subsidence, inclination, curvature, horizontal movement and horizontal deformation of the expressway by applying the scientific research achievement of the movement and deformation of the overlying layer after the coal mining, evaluating and judging the safety and putting forward safety measures have become new subjects of researchers for coal mining under building, water body and railway. In light of the features of the expressway in mountain areas and taking Qijiang-Wansheng Expressway as example, the effect of the underground coal mining on the expressway was systematically studied and the mining-caused damage evaluated. Preliminary discussion was made on the coal mining under the expressway in operation and the technical measures for the safety were proposed.
