摘要

采用现场调查、数值模拟与理论分析相结合的研究方法，对圆梁山隧道岩溶突水的机理及其防治技术进行了系统地研究，揭示了隧道岩溶突水是受水压、岩溶充填物与隧道围岩塑性区范围等影响的渐进破坏过程，总结了隧道岩溶突水机理，并针对圆梁山隧道揭示的溶洞情况，制定了岩溶突水的防治原则，实现了复杂岩溶条件下安全、高效的施工效果。

Abstract

By means of investigation on the engineering geological conditions

numerical modeling

and theoretical analysis

the mechanism of the karst water burst and its prevention countermeasures in Yuanliangshan tunnel are researched systematically. The results show that the karst water burst in tunnels is a gradually developed process

which is influenced by water pressure

different filling materials and the plastic zones around the tunnel. The mechanism of the karst water burst in tunnels is summarized; and in light of the karst conditions exposed in Yuanliangshan tunnel

the principles for preventing the karst waterburst are established. Thus

construction of tunnels under complex karst conditions with safety and high efficiency has been achieved.
