以地下水环境动态平衡为出发点,根据前期研究基础得到的植被合理生态用水量及排水量控制值,进行六盘山特长隧道排水分区的划分,并结合复合衬砌量化渗透系数推导六盘山隧道不同区段最大控制水位,进而为注浆圈设计参数提供计算依据,最大限度保持生态环境的稳定。 Taking the dynamic balance of groundwater environment as starting point, the division of drainage division of Liupanshan extra-long tunnel was conducted according to the rational ecological water consumption of vegetation and displacement control value obtained from previous research. The maximum control of different sections of Liupanshan tunnel was deduced based on the quantitative permeability coefficient of composite lining Water level, and then provide calculation basis for grouting circle design parameters to maximize the stability of the ecological environment.
