准确预算隧道涌水量能有效减少隧道病害,保护生态环境,科学指导隧道的设计与施工。通过Visual Studio2010软件开发平台,基于“地下水动态平衡”的设计理念,采用经典的计算方法,完成特长隧道涌水量计算和控排标准的制定。并以六盘山隧道某段为例,进行实例验算,根据围岩渗透系数、地下静止水位高度、洞室尺寸、含水层厚度等因素计算得出总涌水量,根据植物蒸散法制定排水量控制标准。结果准确可靠,避免了重复、繁琐的计算工作,提高了计算过程的规范化、智能化和工作效率。本研究对于山岭隧道涌水量预测软件开发具有一定的参考价值。
Accurate budget tunnel water inflow can effectively reduce the tunnel disease, protect the ecological environment, scientific guidance tunnel design and construction. Through Visual Studio2010 software development platform, based on the design concept of “groundwater dynamic balance ”, the classic calculation method is used to calculate the gushing water amount of super long tunnel and to set the standard of control and discharge. Taking a section of Liupanshan Tunnel as an example, an example calculation is made. The total water inflow is calculated according to the permeability coefficient of surrounding rock, the height of underground still water, the size of cavern and the thickness of aquifer. The control standard of displacement is formulated according to plant evapotranspiration method. The results are accurate and reliable, avoiding repetitive and cumbersome calculation work and improving the standardization, intelligence and work efficiency of the calculation process. This study has certain reference value for software development of mountain tunnel water inflow forecasting.
