【摘要】 本文针对甘肃省内外部分黄土公路隧道防排水方面存在的问题,首先根据黄土层地下水运规律,按水力学渗流原理并应用地下水动力学法和地下水径流模数法等方法,探讨了黄土层地下水情特性、隧道渗透涌水量估算和水对围岩稳定性影响的分析计算方法。然后在总结现有公路隧道防排水技术特点的基础上,提出了黄土公路隧道防排水系统宜采用复合防水层为主的适用技术与结构型式,得出了一些有益的结论。
【Abstract】 This paper states on the problems in water preventing and draining of highway tunnel of loess in Gansu Province and near area.Firstly,it discusses the method to analyze and calculate the affect of groundwater characteristic,estiniate of tunnel water quantity and the varying of water contained in loess to the stability of surrounding rock mass according to the principle of groundwater leaking, hydraulic penetrating principle, groundwater dynamic law, groundwater flowing modulus low and so on. Secondly, it brings forward that it is a practical technical and structure mode to use the multiple preventing layer as the water preventing and draining system in highway tunnel of loess.
【Key words】 highway tunnel of loess; water preventing and draining system; structure mode; groundwater leaking; groundwater dynamic law; FEM;
