摘　　要：介绍了渝武高速公路复线(北碚至合川段)TJ-2合同段中梁山隧道斜井XJK0+695~XJK0+747段穿越的溶洞的规模与形态特征,提出了斜井通过该溶洞的处治方案:采用综合超前地质预报手段探明岩溶规模、形态特征,制定了调整支护参数、调整开挖工法等安全施工措施,并介绍了该方案实施的具体步骤,最终顺利通过了该溶洞。This paper introduces the scale and morphological characteristics of the karst cave traversed by the inclined XJK0+695~XJK0+747 section of Zhongliangshan Tunnel in the TJ-2 contract section of Chongqing-Wusheng Expressway(Beibei to Hechuan section), and proposes the solution through the karst cave: the comprehensive advanced geological prediction method was used to verify the scale and morphological characteristics of karst, and the safety construction measures such as adjusting the supporting parameters and adjusting the excavation method were formulated, and the concrete steps of the implementation of the scheme were introduced. Finally, the karst cave was successfully passed.
