强震区高拱坝抗震安全研究

从2008年"5.12"汶川大地震到今年"4.14"玉树地震,西部强震区高拱坝的抗震安全问题成为坝工界密切关注的问题。从我国强震区高拱坝抗震研究与工程建设中现存的问题出发,分析并总结了高拱坝地震破坏机理和高拱坝抗震设计理念(包括抗震评价准则、混凝土材料动力特性研究、高拱坝抗震设计分析等)的研究与发展,指出了当前高拱坝抗震较为适用的抗震措施,为今后的研究提供参考。

Study on seismic safety for high arch dam in meizoseismal area

In view of ＂5·12＂ Wenchuan earthquake in 2008 and ＂4·14＂ Yushu earthquake in this year, the seismic safety of high arch dam in western regions maintains a close community concern. This article is starting from issues of the seismic study and construction of high arch dams in China strong earthquake belt, analyzes and summarizes researches and development of the failure mechanism and anti-seismic design of high arch dam （including seismic evaluation criteria, dynamic properties of concrete materials, seismic analysis and design of high arch dams, ere）. This article also make a summary of arch earthquake-resistant measures, pointing out the more applicable measures of the high arch dam to the seismic earthquake as a reference for future research.
