| 摘 要： | 本文首先叙述用两种方法(倾角变位法和角变位移法)分析水电站厂房的自振特性。再用实验结果进行校核验定。结果表明:倾角变位法不如角变位移法。物理推理也可知其正确性,前法忽略了各杆件的轴向变形,即忽略了竖向振动特性。模型实验结果证实了这个论点。依此,本文提出了一种简便易行的分析方法用来确定水电站厂房的自振特性。

| Abstract: | The analysis of free vibration Of hydropower house by means of two methods are deformation of inclination angle and slope deflection. Model tests were also carried out and comparisons made as justification. Conclusion shows that the analysis method of deformation of inclination angle is inferior to that of slope deflection. The reason is that the neglect of axial deformation of each member has to lead the neglect of vertical vibration effect. Model test result certified it too. A more feasible analysis method for the free vibration of hydropower hoase is developed. |
