昔榆高速太行山特长隧道水文地质条件概述

Overview of hydrogeological conditions of Taihang Mountainextra long tunnel of Xiyu Expressway

昔榆高速太行山特长隧道的水文地质条件复杂,通过对该隧道的流域、水系、地层等进行梳理研究,可划分为槐河流域、刀把口河流域、杨赵河流域,含水岩层以裂隙水若富水层为主。对该隧道涌水量预测方法及结果进行比较评价,各预测方法预测结果差距较大,对多种方法预测结果进行综合考虑可作为设计依据,但应采用动态设计方法,为工程的顺利进行提供一定的技术支持,为类似隧道水文地质条件研究和涌水量预测提供参考。

The hydrogeological conditions of Taihang Mountain super long tunnel of Xiyu expressway are complex.Through combing and studying the river basin,water system and stratum of the tunnel,it can be divided into Huaihe River Basin,daobakou River Basin and Yangzhao River Basin.The water bearing rock layer is mainly fissure water rich water layer.The water inflow prediction methods and results of the tunnel are compared and evaluated.The prediction results of each prediction method have a large gap.Comprehensive consideration of the prediction results of various methods can be used as the design basis,but the dynamic design method should be adopted to provide certain technical support for the smooth progress of the project and provide reference for the study of hydrogeological conditions and water inflow prediction of similar tunnels.
