At this instant, bottom plates experience large slamming pressure, which can damage bottom plates. the major content of this thesis is to calculate slamming pressures and ultimate bearing capacities more rationally by probabilistic analysis method, and to estimate the safety by reliability analysis method
本文的主要內容就是在考慮各種不確定性因素影響的情況下，用概率分析的方法較為合理地計算作用在底板上的砰擊壓力和底板極限承載能力，並用可靠性方法合理評定底板的安全性。 -
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
若這些海上建築物的上部結構底高程較低，在惡劣海況下當大波浪在其面板下面通過並與之接觸時，面板下面除了作用有強度變化較緩慢的波壓力外，在波峰剛接觸到面板時尚存在著歷時很短但強度極大的沖擊壓力，這種極強沖擊荷載會引起建築物的整個上部結構失穩或造成局部破壞。
