A STUDY ON THE DESIGN OF PERMEABLE R.C. LINING IN HIGH PRESSURE WATER CARRIAGE TUNNEL
渗水高压引水隧洞衬砌的设计研究

The coupled analysis model of uniform seepage flow force and earth stress field is set up, and the formula established based on test results, which shows the permeability coefficient varies with stress level. On the basis of concrete lining deformation character with crack emerged, a design method of high pressure water carriage tunnel lining is put up. Then the FEM program is used in the design and research of the permeable concrete lining for high pressure water carriage tunnel in Guangzhou Pumped Storage Power Plant.
