這種不穩定塊體運動由波浪循環荷載誘發，其結果使底床整體坡度減緩，水深加大，而且不穩定的塊體運動具有小區域、多發性和溯源侵蝕的特點，將繼續影響著海域以後的水深地形的發展演化，並不斷改變著該區的流場與底床地層條件，對構築物地基土的穩定性產生著動態的影響。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。It decreased with the increase of the gradient. the soil moisture in sunlit slope is greater than that in sunless slope, and changes as the following order in the slope : top < middle < lower
在坡面，隨著坡度的增加，土壤含水量逐漸降低；陰坡的土壤含水量高於陽坡；而在同一坡度和坡向，土壤含水量從坡底向坡頂遞減。This discovery lends credence to the controversial idea of forcefully injecting water or steam into faults at the base of an unstable flank to trigger the stress - relieving earthquakes needed to let it down slowly
這項發現無疑為一個爭議性的構想打了一劑強心針：在不穩固邊坡底部的斷層，強行注入水或蒸氣，目的是引發地震、釋放應力，以緩慢降低邊坡坡度。Through analysis, we conclude that washing action of wave and flow is main power of evolvement of region of interest landform, structure lead to the fact that water area around shallow structure in cheng dao sea field has an increase about 0. 3m / a through actual measurement, water depth increase rate around foundation is 0. 25m / a, slope gradient of side slope averagely has a decrease of 5 % o a year, however marine hydropower wash rate through compute is 0. 2m / a on underwater bottom, the wash rate on structure foundation is 0. 35m / a
分析認為，浪流的沖刷作用是研究區水深地形演化的主要動力，構築物的存在，使埕島海域淺水區人工構築物周邊水域實測年水深增加幅度約0 . 3m a ，地基附近水深增加速率0 . 25m a ，邊坡坡度平均每年以5減緩，而計算得出的海洋水動力沖蝕速率在水下底坡為0 . 2m a ，在構築物地基沖蝕速率達0 . 35m a 。The model for non - linear long wave and the mild slope equation are respectively applied to simulation wave propagation on a classical topography for small size waters - submerged shoal with concentric contours. the differences between them in wave propagation are got through comparing the numerical solutions. and the results are accordant with actual cases
