为了开展混凝土重力坝在空库和满库情况下的振动状态研究,提高对其抗震性能的认识,由国家地震局工程力学所和广东省水利电力勘测设计研究院及白盆珠水库管理局合作,对西枝江混凝土坝用635型偏心质量块起振机迫振和脉动方式,先后进行了坝体有振特性以及坝与基岩和库水的动力相互作用等问题的振动试验研究。西枝江水利枢纽工程位于广东省惠东县境内的西枝江上游的白盆珠峡谷中,它的拦河坝是一座混凝土空心重力坝,坝高64.2米,坝顶长240米,由十六个坝段组成。水库的总库容为
In order to carry out the research on the vibration state of concrete gravity dam under the conditions of empty reservoir and full reservoir and to improve the understanding of its seismic performance, the cooperation of the Institute of Engineering Mechanics of the State Seismological Bureau and the Bureau of Water Resources and Electric Power Survey, Design and Research of Guangdong Province and Bai Basin Management Bureau , The Xizang River concrete dam with 635-type eccentric mass forcing vibration and pulsation mode, vibration characteristics of the dam has been carried out as well as the dam and bedrock and reservoir water dynamic vibration and other issues of vibration test. Xizhi River Water Conservancy Project is located in the Baipenzhu Gorge in the upper reaches of the Xizang River in Huidong County, Guangdong Province. Its barrage is a concrete hollow gravity dam with a height of 64.2 meters and a crest of 240 meters. It consists of 16 Dam section composition. The total storage capacity of the reservoir is
