Under confused sea condition , the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface . previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs , followed by a slowly - varying uplift pressure of less magnitude but of considerable duration , and which typically is first positive , then decreases to zero and becomes negative , in hostile sea state , the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed 若这些海上建筑物的上部结构底高程较低，在恶劣海况下当大波浪在其面板下面通过并与之接触时，面板下面除了作用有强度变化较缓慢的波压力外，在波峰刚接触到面板时尚存在着历时很短但强度极大的冲击压力，这种极强冲击荷载会引起建筑物的整个上部结构失稳或造成局部破坏。
