Structural matter drops to hit water with fixed rate phut from certain height, inchoate and main the structure that attacks water process in the light of phut is answered begin research, and press mutation of field of force and Xing Bo to wait to study however to entering the underwater after water less, and add with each passing day as large bridge and marine project much, the construction in these projects and the phenomenon that phut of large construction content also appeared to hit water in use process, like Guangdong 9 rivers big bridge is bumped to break down after collapsing, large area bridge floor falls into surface to wait, the meeting such as mutation of field of pressure of the underwater after this kind of phut hits water and Xing Bo is right all round structural products gives birth to certain influence, evaluate this kind of influence to have real project sense to construction and design.

结构物从一定高度落下以一定速度砰击水面，早期主要针对砰击入水过程的结构响应开展探究，而对入水后水下压力场突变和兴波等却探究较少，而随着大型桥梁和海洋工程日渐增多，在这些工程的施工和使用过程中也出现了大型结构物砰击入水的现象，如广东九江大桥被撞垮塌后大面积桥面落入水面等，这种砰击入水后水下压力场突变和兴波等会对四周结构物产生一定影响，评价这种影响对施工和设计具有现实的工程意义。
