多重不良地质条件隧道开挖稳定性与突水预防研究
Stability Analysis of Tunnel Excavation and Prevention of Water Inrush in Multiple Adverse Geology
摘要
Abstract
Aiming at the stability of working face when the tunnel passes through t adverse geological superposition ar-eas,taking the Zhongliangshan Tunnel of Chongqing Railway Line 27 as the engineering background,the in-fluence of multiple adverse geology on the change of surrounding rock seepage field,displacement field and plastic zone during tunnel excavation was studied by the three-dimensional fluid-solid coupling numerical method.Corresponding safe thicknesses for water inrush prevention are obtained.The results show that the su-perposition of multiple adverse geological conditions will intensify the water inrush disasters in tunnels,and early prevention is needed.Different thicknesses of rock mass for water inrush prevention should be reserved according to the distribution of adverse geological conditions.关键词
