| 摘 要： | 在借助渗流体积力考虑渗流场的力学效应，并由室内试验获得渗透系数随应力水平而变化的关系式的基础上，建立了裂缝混凝土衬砌和渗水围岩地层中渗流场与应力场的耦合计算模型，然后根据衬砌混凝土裂缝出现和开展后的受力变形的特征，提出了一种可供高压引水隧洞衬砌配筋采用的计算方法，并将其应用于广蓄电站二期工程高压引水隧洞衬砌的设计研究。

| Abstract: | 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. |
