Based on the equilibrium section principle and by decompaction correction, the profiles of the Cenozoic structural evolution in the north of the Dongying Sag, the Bohaiwan Basin and the paleostructural map s of the subface of the Sha-3 Member before the sedimentation of the Sha-1 Member and the Guantao Formation were compiled.

根据平衡剖面原理、经过去压实校正编制了渤海湾盆地东营凹陷北部地区新生代构造演化剖面图以及沙一段沉积前和馆陶组沉积前的沙三段底面古构造图，并从演化剖面和平面古构造两方面入手进行研究，较系统地总结了该区新生代构造演化特征。

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。
