摘　　要：随着西部山区引水工程的增加,工程地质条件也愈加复杂,其中高地温问题尤为突出,给过水隧洞修建带来了严峻挑战。文章针对高温过水隧洞中围岩的温度场规律及稳定性、衬砌结构的热应力规律、衬砌材料、稳定性影响因素等方面,系统总结了近年来高温过水隧洞围岩及衬砌结构稳定的研究进展,对未来该领域进一步发展,提出了一些研究方向。With the constructing of water diversion projects in the western mountainous areas,the engineering geological conditions encountered are more and more complex,especially the problem of high ground temperature,which brings severe challenges to the construction of diversion tunnel.This article systematically summarizes the stability of surrounding rock and lining structure of high-temperature diversion tunnel in recent years in terms of the law and stability of temperature field of surrounding rock in high-temperature diversion tunnel,lining structure thermal stress law,lining material research,influencing factors of stability and so on which has proposed some research directions for the further development of this field.
