| 摘 要： | 船舶撞击桥墩是一个复杂过程，确定桥墩基础承受撞击力的能力也需经过复杂计算，工作量非常大。通过对多座典型桥梁基础在冲击作用下的动力响应与静力响应之间的比较，得到桥墩基础动力放大系数的一般规律。在较短时间进行动力计算的情况下，桥梁设计人员应用该规律可较准确地估计桥墩承受船舶撞击的能力。

| Abstract: | The impact of ships to piers is a complicated process and the determination of capability of pier foundation withstanding impact also needs complex calculations with a great number of workloads.Based on the comparison between the dynamic and the static responses of many typical bridge foundations under the impact,this paper obtains a general rule of the dynamic magnification coefficient of pier foundation.On condition that the dynamic calculations are carried out in short period of time,the bridge designers... |
