摘要
六沾铁路复线乌蒙山一号隧道工程穿越梅花山主脉,工程地质和水文地质条件复杂。结合地质调绘、物探、钻探、水文地质试验及室内试验资料,论述隧道通过的地层富水性、蓄水构造、水文地质单元,以及地下水的补给、径流、排泄条件,采用降水渗入法和地下水动力学法对隧道涌水量进行预测和评价,提出了隧道可能发生涌突水危险性的段落及相应的对策建议,供隧道防、排水设计参考。
No. 1 Wumeng Mountain Tunnel of Liupanshui-Zhanyi Double-track Railway passes through the main cordillera of Meihua Mountain, where the engineering geological conditions and hydrological conditions are complicated. By geological survey, geophysical prospecting, drilling, hydrogeological test and laboratory test data and so on, the water abundance, water-storage structure, hydrogeological unit of the strata and the supply, runoff and drainage conditions of groundwater in the tunnel area have been dissertated, the watergushing amount has been estimated and evaluated through the rainfall infiltration method and groundwater dynamics method, and suggestions of engineering measures are made for the tunnel section with potential water- gushing hazard to provide references for the tunnel design of waterproof and drainage.
