首次将条分法引入到充填型岩溶蓄水构造突水、突泥研究当中,基于边坡稳定性分析的条分法原理,对隧道-岩溶充填物-岩溶管道系统进行了抽象概化,建立了充填型岩溶蓄水构造充填物条分解析计算模型。假设充填物在滑动面上各处均达到极限平衡状态,且在滑动面上的破坏服从Mohr-Coulomb破坏准则,通过力的平衡条件推导了充填型岩溶蓄水构造突水突泥的最小安全厚度计算公式,形成了一种求解充填型岩溶蓄水构造突水、突泥最小安全厚度的工程实用解析方法。该方法为岩溶隧道突水、突泥计算提供了一种新思路,计算结果与数值计算吻合性较好且符合实际工程情况,具有一定的理论研究与工程应用价值。
For the first time, striping method is introduced into the study of water inrush and mud in filling karst water storage structure. Based on the principle of strip method of slope stability analysis, the tunnel-karst filling-karst pipeline system is abstractly generalized and established Fractional analysis and calculation model of filling karst storage structure filling. It is assumed that the filling reaches the limit equilibrium everywhere on the sliding surface, and the failure on the sliding surface obeys the failure criterion of Mohr-Coulomb. The minimum safety thickness of the water inrush Calculation formula, a practical analytical method for solving the minimum safety thickness of water inrush and filling mud in filling karst water storage has been established. The method provides a new idea for calculation of water inrush and mud in karst tunnel. The calculated result is in good agreement with the numerical calculation and in line with the actual engineering situation, which has certain theoretical research and engineering application value.
