摘要
对船队撞击大桥桥墩能量计算中的能量折减系数Ng进行了定量分析,提出了Ng的计算方法和公式,分析了Ng与其他参数的关系,说明了以前估算中存在相当大的误差,解决了大桥桥墩防撞领域的一个关键性问题——能量定量计算问题。
The energy attenuation coefficient N g for a fleet when it hit a pier is quantitatively studied. The calculating method and formula for N g are presented. The relationships between N g and the other parameters are analyzed. It has been found that rather large errors may have existed in former calculations of N g. A crucial problem, the quantitative calculation of energy, is solved in the field of pier collision prevention. An example is given.
