| 摘 要： | 根据Harr(1962年)提出的镜像理论和Fernandez(1994年)所做的基本假定推导出不透水覆盖层下压力隧洞外渗透水压力和渗流有效应力,结果表明,隧洞内水渗透会在不透水面上产生较大的水压力;隧洞外渗流有效应力为拉应力,其影响范围与隧洞和不透水面的距离直接相关,这与传统弹性力学方法将内水看作机械荷载求解结果明显不同。 |

| Abstract: | It derives water pressure outside pressure tunnel under water-tight layer and effective stress of seepage from the mirror image theory raised by Harr(1962) and the basic proposition raised by Fernandez(1994).It shows water leaking in tunnel produces big water pressure to water-tight layer,effective stress of seepage outside tunnels is tension stress and its influencing range is relavant to the distance between tunnel and water-tight layer,which is obviously different from the traditional flexible mechanics which sees interior water as mechanical loading. |
| Keywords: | pressure tunnel effective stress seepage leaking pressure |
