引汉济渭引水隧洞穿椒溪河段突涌水数值模拟
|
摘要
陕西省引汉济渭工程引水隧洞突涌水问题是制约工程顺利开展的关键技术问题之一。针对横穿椒溪河段的典型区段突涌水问题,采用ADINA软件建立水文地质概念模型,计算不同工况下该区段的地下水位、流速矢量、涌水量等。结果表明:断层位置受开挖扰动影响较大,出现了集中渗漏,因此在断层位置极易形成渗漏通道,发生突涌水。
Shaanxi Hanjiang River to Weihe River diversion tunnel water inrush problem is one of the key technical problems that restrict the smooth development of the project.In this paper,aiming at the problem of water inrush in the typical section of acrossing Jiaoxi River,the ADINA software was used to establish the hydrogeological conceptual model,and the variation law of the groundwater table,the velocity vector and the water inflow were calculated under different conditions.The results show that the fault location is greatly affected by the excavation disturbance,and there is concentrated leakage.Therefore,it is very easy to form the leakage channel and occur the water inrush in the fault location.
