【摘要】 我国西南部地区新建和在建的一些大型水电站工程中地下发电厂房均形成主体为大型岩体的地下洞室群,合理估计地震作用下这些大型地下洞室群的反应是一个亟待解决的问题。为了对水工地下厂房岩体洞室结构地震反应数值分析问题进行探讨,回顾了该类工程在我国的发展现状,总结了该类工程的结构特点和震害特点,并基于一些典型的地下洞室地震反应数值分析结果,阐述了水工地下厂房岩体洞室地震反应数值分析中应当关注的问题和研究方向。更多还原

【Abstract】 In southeast China, there are several hydropower stations including large scale underground rock caverns have been built and some are under construction. It is the first thing how to evaluate reasonably the seismic response of these large scale underground rock caverns because earthquake happens frequently in southeast China. For discussion on the numerical study on the seismic response, we review the progress of the underground hydropower station project in China, and summary the engineering characteristics of the project and the damage specialties under earthquake. Finally, we point out some important problems and progress directions on seismic response numerical study on underground cavern in hydropower station, based on the conclusion in some typical cases of the study.更多还原
