某地下水封洞库涌水量模拟计算

Simulation Calculation of Water Inflow of a Groundwater Sealed Cavern

涌水量是影响地下水封洞库安全施工和稳定运营的重要因素,合理估算涌水量对该项目具有重要的意义。该文基于岩体的流固耦合理论,采用COMSOL Multiphysics软件对地下水封洞库开挖后有无水幕工况情况下的涌水量进行模拟计算。该计算方法对其它类似的地下水封洞库工程具有借鉴指导意义。

The water inflow is an important factor that effects the safe construction and stable operation of groundwater sealed cavern,and reasonably estimating the water inflow has great significance for this project. In this paper,based on the fluid-solid coupling theory of rock mass,the water inflow is simulated by using the COMSOL Multiphysics software under the engineering condition of having or not having water curtain after excavating the groundwater sealed cavern. The calculation method has some reference significance for other similar groundwater sealed caverns.
