隧道围岩影响突泥灾害的数值模拟研究

Simulation Study on the Influence of Surrounding Rock to Mud Inrush in Fault Tunnel

随着我国隧道与地下工程修建数量越来越多、地质条件日趋复杂,在修建过程中遇到不良地质情况不可避免。隧道发生的突泥灾害是我国隧道建设过程中重要的待解决问题之一。以已有数值模拟方法为基础,运用有限元方法对围岩情况如何影响突泥进行了数值模拟,研究分析了围岩情况对隧道突泥的影响,通过分析得出围岩情况变差、围岩渗透性变大时,突泥灾害发生的几率将会变大,并将研究结果应用到工程实践中,对工程施工起到重要的指导作用。

With the vigorous development of tunnel engineering in our country,the problems encountered in the course of tunnel construction are increasing. Among them,the mud inrush disaster in tunnel is one of the important problems to be solved. In this paper,numerical method is used to study the influence of surrounding rock on tunneling,and the results are applied to engineering practice,which plays an important role in engineering construction.
