本文以东毛高速六盘山隧道为依托,根据六盘山隧道实地考察、地勘报告及气象数据,基于地下水动态平衡理念,将植被生态需水量引入水环境恢复平衡公式中,通过六盘山隧道涌水量计算、隧址区植被生态需水量计算、水平衡恢复计算得到了六盘山隧道控制排水量,并对比不同时期六盘山隧道进出口排水量监测数据,达到了动态保护隧址区地下水环境的目的。 Based on the Liupanshan tunnel site investigation, geological survey reports and meteorological data, based on the principle of dynamic balance of groundwater, the paper introduces the ecological water requirement of vegetation into the water environment recovery balance formula, Calculation and calculation of ecological water requirement of vegetation in tunnel area, and the displacement control of Liupanshan tunnel calculated by water balance recovery, and compared the monitoring data of displacement at the entrance and exit of Liupanshan tunnel in different periods to achieve the purpose of dynamically protecting the groundwater environment in the tunnel area.
