为研究富水地层特长公路隧道斜井突泥涌水事故的致灾成因，该文以梁王山隧道斜井为工程背景，采用现场调研、理论分析和现场测试等方法分析了突泥涌水事故机理，提出非完整岩体隔水层裂隙型的灾害模式，制定了“斜井改线、排水加固、帷幕注浆、大管棚超前支护和增强支护结构”的综合处置措施。现场监测结果表明，处置后斜井支护结构处于稳定状态，证明了处置措施的有效性。

In order to research the causes of mud and water inrush accidents in the inclined shaft of a long highway tunnel in rich water strata, taking the Liangwangshan Tunnel inclined shaft as the engineering background, the mechanism of mud and water inrush accidents is analyzed by methods such as on-site investigation, theoretical analysis, and on-site testing. A fracture type disaster mode of incomplete rock mass waterproof layer is proposed, and a comprehensive treatment measure of “inclined shaft rerouting, drainage reinforcement, curtain grouting, large pipe shed advanced support and support structure enhancement” is formulated. The on-site monitoring results indicate that the inclined shaft support structure is in a stable state after treatment, proving the effectiveness of the treatment measures.
