| 摘 要： | 涌突水是我国西南山区修建地下工程过程中经常遇到的问题之一。文章以锦屏二级水电站引水隧洞为例,引入等效入渗强度来模拟降雨入渗过程,采用等效连续各向同性介质模型,运用三维有限元的基本方法和地下水动力学的基本理论对引水隧洞施工全过程工程区涌水量和降落漏斗的影响范围开展了分析研究。在不采取相应的防渗支护措施的情况下,洞群开挖将产生最大26 m3/s左右的涌水量,降落漏斗的影响范围在20 km左右。采取"以堵为主、堵排结合"的工程措施后,涌水量明显减小,地下水位得到回升,处理结果基本可以满足工程建设和地表水环境的需要。 |

| Abstract: | Water outburst,which often occurs in the underground construction,is one of the problems at mountainous areas in the southeast of China.Taking the Jinping Cascade II Hydropower Station for example,the paper introduces the equivalent infiltration intensity method to simulate the rainfall infiltration,which is based on the equivalent continuous isotropic medium model.With the basic tool of three dimensional finite element method and the basic theory of groundwater dynamics,the water inflow and cone of depress... |
