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。The change of dynamic pressure in the orientation of wave spreading follows the damping of e - index 6
5 、堤心內沿波浪傳播方向變化的動壓遵循e指數衰減規律。A time - variant reliability formulation is presented in this paper to account for the effects of fatigue, corrosion and maintenance actions on the first yield reliability of midship section modulus. a probabilistic model for long - term distribution of wave - induced fatigue stress range is established. for the purpose of obtaining the performance of structure that stands random fatigue load, the concept of stress parameter and equivalent stress range are introduced
船舶在由波浪彎矩引起的交變應力作用下，船體構件焊接點處的微小裂紋逐漸擴展；同時，隨著船齡的增加，眾多結構構件遭受腐蝕的作用；從而使船體梁剖面模數減小，船體梁承載能力衰減，船舶結構的安全性將受到相當大的影響。
