波浪基部
英文
wave base-
In coast and offshore engineering, the safety of the structures whose superstructures located in the splash zone such as piled wharves, shore trestles, oil drilling platforms, etc, have great relation to wave slamming
在海岸和近海工程中，近海採油平臺、樁基碼頭和海上棧橋等上部結構位於浪濺區的建築物的安全與波浪沖擊作用關系極大。Based on the data on scour around large diameter cylinders exposed to waves and currents, effects of every kind of sea enviromental parameters on maximum scour depth are analyzed and guided by dimensional analysis and multidimensional linear regression, an equation is given to compute maximum scour depth around large diameter cylinders in combined waves and currents. compared with some other equations, this equation is more accrete, simpler and clearer and the compute d results are in good agreement with experimental ones
本論文主要是在總結國內外研究成果基礎上，從波浪與水流共同作用下海床上直立大直徑圓柱建築物周圍的局部沖刷機理出發，研究和探討了圓柱周圍的沖淤形態；分析各種海洋環境參數對最大沖刷深度的影響，並利用已取得的實驗資料，採用量綱分析原理和多元線性回歸分析方法，建立一個波流共同作用下海床上直立大直徑圓柱建築物周圍的最大沖刷深度計算公式。In part i, based on the systematic review of the study history and prospect of nwt, the detailed process of a 2 - d nwt model developed independently is reported. the two key discretization methods, boundary element method ( bem ) and mixed eular - langurange ( mel ) method, are introduced in detail, and an integrated flow chart of the detailed time - domain simulation steps of nwt is presented
第一部分在回顧數值波浪水槽發展歷程、現狀及其應用前景的基礎上，重點報告本人獨立開發二維非線性數值波浪水槽模式的研究工作，其中包括構建數值波浪水槽的運行原理和具體步驟等全過程。The effects of waves transformation, refraction, diffration, reflection and breaking are all due to the depth of water, varying topography, bottom friction, obstacles and current as waves proceed from offshore to near shore regions. some basic parameters which are relevant to the cost of buildings as well as the type of structures are determined by the wave factors since these projects are placed in near shore area, so it is of great importance to study the regularity of wave transforming
外海波浪傳入近岸淺水區受水深、地形、底摩擦、障礙物以及水流等因素的影響，會發生變形、折射、繞射、反射和破碎等各種現象，然而大部分海洋及海岸工程位於近岸地區，該地區的波浪要素將是確定工程造價、建築物型式等最基本的參數，因此研究近岸地區波浪的變化規律具有重要意義。In the storm, the part on surface layer of the underlying bed will produce the liquefaction, the absolute standing wave that form the front of the structure may bring 6. 16 meter depth of the liquefaction, so the foundation of structure will lose part of the supporting force, the structure will slide in this situation. that is to say, because of the foundation partly liquefaction, the exist of soft layer and the component force of gravity, the structure slide further to the basin and collapse, which leads to disastrous consequence
在強暴風浪下，底床表層1 . 75米以上均有可能產生液化現象，而在構築物前形成的完全駐波，甚至能夠造成6 . 16米的液化深度，構築物地基部分失去支持力，將直接導致構築物的滑動，也就是說，在地基部分液化、軟弱層的存在以及構築物沿坡重力分力的共同影響下，構築物將向「盆」底方向發生更大的滑動，甚至可能發生倒塌。分享友人
