岩溶隧道涌突水原因分析及治理技术探讨

对岩溶发育特征与涌突水的关系作了深入介绍并给出了判断标准，提出岩溶涌水与气温、降雨量和降雨强度、施工引起的应力分布等因素有关，通过数值模拟和理论分析阐述了岩溶突水的止水岩柱受拉破坏、裂隙剪切破坏、裂隙水力扩张、块体失稳破坏等突水机理，并对突水压力和突水量的估算和岩溶治理技术做了介绍。

Cause Analysis and Countermeasures for Water Gushing of Karst Tunnels

The relationship between the karst development features and the water gushes are presented in detail and assessment criteria is proposed; it is proposed that the karst water gushes are related to the atmospheric temperature, rainfall and rainfall intensity and the stress distribution caused by the construction; the water gushing mechanisms, such as the tensioning failure of the water sealing rock columns, the shearing failure of the fissures, the hydrodynamic expansion of the fissures and the stability losing failure of the ground, are expounded by means of numerical analysis and theoretical analysis; the estimation of the water gushing quantity and the water gushing pressure, as well as the karst treatment technology, are presented.
