ANALYSIS OF THE SYSTEM OF DEEP CONFINED KARST WATER
OF YUANLIANGSHAN TUNNEL IN THE MAOBA SYNCLINE
摘要
Abstract
The Maoba syncline takes on trough physiognomy. It consists of two protruding legs and a concave core and is encircled by gigantic thick sandrock, shale and argillite of Silurian. Its core is composed of limestone with thin shale and argillite interlayer of Permian and Lower Trias layers. According to the surface survey, deep-drill prospecting, pumping test and H-O isotope measuring, the paper concludes that the karst water layerly develops in the Maoba syncline that tunnel goes through. There are three layers of water: water in T1d layer, water in P2w+c layer and water in P1q+m layer, and they are independent each other. The above shows that a system of deep confined karst water lies in the core of the syncline. It has hydraulic contact with the east and west legs by way of circling the axes and confined flux along fault belts in some part of the Maoba syncline. The amount of the deep water system is limited in the whole water cycle of the syncline. Waterproof steps should be taken during the construction of the tunnel.关键词
