摘要
通过对江口水电站超薄双曲拱坝典型部位施工期和工程下闸蓄水初期应力应变监测资料的计算,分析了监测断面内的混凝土应力应变大小、变化规律、分布情况以及影响因素等.在基本了解了该拱坝各个部位的受力变化、分布规律、应力变幅及其稳定性的基础上,对整个建筑物的运行实态有了比较准确的把握;同时也验证了设计.
Through the calculation made on the monitoring data of stress-strain in the typical parts on the dam body of the arch dam for Jiangkou Hydropower Station in Chongqing during the construction and the initial impounding period, the amplitude, the changing law, the distribution and the effects of stress-strain on the concrete of the monitoring sections are analyzed hereinafter. Based on the basic understanding of the status of stress-strain in all the parts concerned of the dam and the stability therein, a more exact knowledge on the actual operation condition of the whole structure is obtained, and then the original design of the dam is validated as well.
