另外當波浪離開上部結構底面時產生的負壓力作用對混凝土結構的耐久性也是一個很大的威脅。Through analyzing bed ' s response to wave, in the condition that super - stratum is more hard and second - stratum is more soft in region of interest, super static interstitial hydraulic pressure amplitude die away rapidly between stratums, before in sight of boundary between hard and soft stratum, plane effective pressure increase to max. shear stress reach peak value when bed thickness is approximately 2. 7 meters, then it will decrease to the minimum on the place where the flexible soil has a common boundary with the rigidity, so the boundary is the most destroy plane on engineering. on the basis of reconnaissance in situ, in normal situation of sea, the structure slides to the basin along the boundary
通過對底床在波浪下的響應分析，對于研究區底床上層較硬而第二層較軟的情況，超靜孔隙水壓力幅值在層間交界處迅速衰減，在臨近硬、軟地層交界處前，水平有效應力增至最大，剪切應力在底床厚度大約2 . 7米左右達到峰值，然後減小，到硬、軟層土交界位置，達到最小，因此這個界面就是最容易發生破壞的工程軟弱面，現場勘查證明，即使在正常海況下，構築物也會沿坡以此交界面為滑動面，緩慢向「盆」底滑動。Based on the experimental results for different wave height, wave period and the relative clearance of underside of the wharf deck, the properties of wave impact pressure on wharf deck are studied. the distribution of impact pressure along the underside of the deck model is analyzed. the influence of different incident wave parameters, structure dimension and relative clearance s / h1 / 3 on the impact pressure is discussed

利用本文方法對某集裝箱船進行了規則波中的船舶運動和水動壓力的理論計算，並與船模水池試驗所提供的多狀態的壓力分佈數據相比較，得出船體表面瞬時壓力的分佈及其隨航速和波浪參數變化的某些規律。In the end, in view of the fact that boussinesq - type equations and the mild slope equations are deduced from different hypothesis conditions and behave differently in simulation of wave propagation, the numerical results of wave propagation effected by strong non - linearity are given by the nonlinear three - dimensional mathematical model which was established for the calculation of 3 - d wave particle velocity and wave pressure and suitable to small size waters of arbitrarily varying depth
最後，鑒于boussinesq型方程和緩坡方程是在不同的假設條件下推導而來，應用於描述近岸水域波浪的傳播變形時具有不同的特點。本報告根據作者所建立的可以對任意水深點流場與波動凈壓力場進行求解、適宜水深任意變化水域非線性波傳播的數學模型，提供了在較強非線性作用下波浪傳播的數值模擬結果。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。On calculation formula of wave impact pressure acting on offshore open structure

但是，由於影響結構疲勞性能的因素十分復雜，如波浪載荷和局部的貨物壓力，各種應力成分的組合，結構的局部細節應力集中，平均應力的影響，結構分身所處的腐蝕環境等等，所以各個船級社有關的規定也不一樣，這樣必然造成各個評估方法之間的差異。When waves propagate over the ocean surface, a sequence of wave pressure is induced on the mudline or seafloor, which causes the coupling interaction between the deformation of soil skeleton and seepage movements of porous fluid
海洋表面傳播的波浪在海水-海床的交界面處施加了循環波壓力，在這種循環波壓力作用下，海床內土骨架的變形與孔隙流體的滲流運動相互耦合。分享友人
