发生地震时,水闸的振动状态与振动特性及地震力的确定等问题是为有关的工程单位所关心的。我们结合江苏嶂山闸的抗震加固工作,进行了现场测试试验、室内动力模型试验及有限单元计算分析,取得了有关水闸的自振特性、水闸上部结构对水闸振动影响及地震力确定等有关资料,并进行了几种加固方案的模拟比较试验,提出了加固设
In the event of an earthquake, the issues such as the vibration status and vibration characteristics of sluice gates and the determination of seismic forces are of concern to the relevant engineering units. In connection with the seismic strengthening work of Yushan Gate in Jiangsu Province, we carried out on-site test, indoor dynamic model test and finite element calculation and analysis, and obtained relevant information on natural vibration characteristics of sluice, influence of sluice superstructure on sluice vibration and determination of seismic force , And carried out several kinds of reinforcement programs simulation comparison test, put forward reinforcement set
