| 摘 要： | 测量了高平潮、低平潮及两潮位之间三个时段某高桩码头工作平台的振动情况,比较了不同潮位下振动的最大位移值.对测量数据进行了分析,发现海浪对结构振动的位移大小影响明显,得到了工作平台的前三阶自振频率.利用两点差法,根据码头平动记录求取了码头沿垂直轴向的码头扭转分量,经计算码头转角在10-7rad量级,码头扭转的转动中心按照...

| Abstract: | Measure the vibration of piled wharf in high water,low water and between two times.The largest displacement of vibration is compared three times.The waves influence displacement of wharf.Natural vibration frequency of wharf is analyzed.Get the rotational components from translational components by difference of two points,the value of translational components is about.The center of rotation is moving and not on wharf in most time. |
