摘　　要：利用 Buckinghamπ定理 ,提出了进行船撞缩尺模型试验的相似判据和主要相似系数。以泉州后渚大桥为实际工程背景 ,通过模拟船撞的缩尺模型试验 ,研究了实际船撞力的大小。试验结果与各种技术规范公式计算结果的分析比较表明 ,美国 AASHTO规范的设计船撞力与试验结果最为接近 。The analogy criterion of model testing of ship collision with bridges is proposed by the theorem of Buckingham in this paper. Based on a practical bridge across the Quanzhou,the scaled model testing on the forces of ship collisions was conducted.The testing result was compared with various code expressions. It's shown that the design force of ship collision specified by AASHTO specifications is in good accordance with the testing result. However, the design force of ship collision specified by current design specifications of highway bridge of China is obviously lower than the testing result.
