摘要： 于桥水库土坝原设计放水洞为无压洞,改建为放水发电两用后变为有压洞,引起水流形态发生改变,致使土坝和放水发电洞产生结构振动现象。为了保证工程安全运行,对放水发电洞的各种荷载组合进行了现场振动检测,取得了振动位移、速度、加速度的系列数据,并据此对工程的安全状态进行了分析和评估。
Abstract: The drain cavity by original design is no-pressure in dam of Yuqiao reservoir. It has pressure after rebuliding in order to drain and generate electricity. The water current form is changed to result in structure vibrating. Loadings are tested in the drain cavity for project safety. Data are obtained on vibrating displacment and speed and acceleration. The project safety condition is evaluated.?
