| 摘 要： | 针对小浪底水库1#孔板洞在249.0 m水位附近(运行水头约113 m)偏心铰工作弧门在局部开启运行工况及连续开启过程中,门体不同部位振动动应力、加速度及动振位移响应结果进行了观测分析,并与2#孔板洞在248.0 m水位附近(运行水头约103 m)工作弧门的振动观测结果进行比较分析,对工作弧门的运行安全作出评价。总之,有关观测成果对类似工程工作弧门的运行操作具有一定的参考价值。

| Abstract: | The vibration dynamic stress，acceleration and dynamic vibration displacement response at various locations of the eccentric-hinge radial gate for the No.1 orifice tunnel of Xiaolangdi Reservoir located near the water level of 249.0 m（the operation water level of about 113 m）under the partially opening condition and during the continuous opening are observed and analyzed，and then the results are compared with those from the vibration observation made on the working gate for the No.2 orifice tunnel near the water level of 248 m（the operation water level of about 103 m）. Thereafter，the safety assessments are made on the operations of the gates. Generally，the relevant observation results have certain reference values for the operation of the working gates of the similar projects |
