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。
Based on a practical bridge across the Quanzhou, the scaled model testing on the forces of ship collisions was conducted.
但是由于振动台本身承载能力、试验时间和经费等的限制，目前在进行振动台模型试验时大多采用缩尺模型进行试验。
But at the present time, Small-scale models have been frequently used for experimental test because of limited testing facilities and economic reasons.
但深海平台的模型试验需要很大的水池，目前世界上还没有一个水池用常规的缩尺比能够进行该项试验。
However, model tests for deep sea platforms require very large model basins and no existing model basin in the world can carry out such tests with traditional scale ratios.
