波浪沖刷 的英文怎麼說
中文拼音 [bōlàngchōngshuā]
波浪沖刷
英文
wash， wave-
What ' s more, we put forward some experienced formulas on the basis of the cortical analysis. the result of the research show that by installing diffluent piers with low ridge, we can eliminate the root of oscillatiny water jump, perfect the energy dissipation effect of water jump, also, we can improve the flow condition of down - stream. the fact that the main flow of down - stream is in the middle, not only effectively lower the speed of the bottom flow in the ridge rear, alleviate the erosion to the river bed, but also avoid the heavy wave resulted from the main flow in the surface, thus improve the surface wave of down - stream obviously. we can work out the body style parameters of diffluent piers with low ridge according to the project flow condition and experience formulas, and then reckon the down - stream surface wave condition for the protected building of the down - stream bank
研究結果表明：設置低坎分流墩后，消除了擺動水躍水舌擺動的根源，提高了水躍的消能效果，改善了下游水流流態。下游水體的主流在中部，既有效的降低了坎后水流底流速，減輕水流對河床的沖刷，又避免了主流位於表面導致波浪過大的結果，下游的水面波浪明顯得到削減。依據經驗公式，可根據工程水流條件設計出低坎分流墩的體型參數，進而估算出下游沿程的水面波浪，為下游岸邊的砌護提供依據。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。Finally, some cases of computation are given, showing that though no obvious nearshore wave - induced currents occur in some water areas before construction of projects, the projects may have great effects on wave induced currents. it is important to study sediment transport and local scour near coastal structures, and much attention should be paid
算例表明，盡管有些水域在工程前波浪並沒有產生較明顯的近岸流，但工程對此的影響可能會很大，這對于建築物附近的泥沙輸移、局部沖刷的研究是重要的，在工程中應引起重視。Based on the local scouring test of the dike ' s head under the action of clear tidal currents, of both tidal currents and waves, and of both muddy tidal currents and waves, variations of the scoured pit ' s depth at each dike ' s head with time, and the scoured pit ' s depths with three experimental conditions are compared
