压力隧洞设计与结构计算研究进展

Advances in Pressure Tunnel Design and Structure Computation

针对目前压力隧洞设计现实和设计规范均不是很完善、结构计算缺乏可靠方法以及对内外水荷载作用下围岩衬砌联合承载机理研究还不深入的现状,对压力隧洞设计准则、结构计算以及内外水荷载作用下围岩衬砌联合承载机理这三个方面的国内外研究进展进行了综述,并指出存在的不足。基于研究现状的总结分析,提出了需要进一步深入研究的课题。研究成果可为压力隧洞的设计和结构计算提供参考。

At present,the design specification of pressure tunnel is not very perfect,the structure computation is lack of reliable method,and the joint bearing mechanism of surrounding rock and lining under the action of internal and external water pressure is not entirely clear in China.The advances in the researches of pressure tunnel design criteria,structure computation and the joint bearing mechanism of surrounding rock and lining under internal and external water pressure in China and abroad are summarized and the shortcomings of these researches are also mentioned herein.The subjects needing to be furtherly studied are proposed and these subjects can provide references to the design and structure computation of pressure tunnel.
