Along with the large-oriented of container vessels, quay wall elevation has been becoming higher and higher, and working load increases continually.
隨着集裝箱船舶的大型化,碼頭岸壁高度越來越大,而且使用荷載也不斷增加。
Understanding the interaction mechanism between the soil and a quay wall composed of large-diameter bottomless cylinders is vital to the safe and economic design of the quay wall.
認識土與沉入式無底大直徑圓筒結構岸壁碼頭之間相互作用機制,對于它的安全和經濟設計至關重要。
Based on dimensional analysis, a number of dimensionless groups that governed the performance of the quay wall were investigated, identified and used to design and interpret centrifuge model tests.
基于量綱分析,首先研究确定了控制這種岸壁碼頭性狀的無量綱項,然後,為研究這些無量綱項的相對重要性,設計了模型試驗,并對試驗結果分析解釋。
Structure computation of sheet-pile wall is a major part in design of sheet pile bulkhead, which is a main form of quay.
闆樁碼頭是一種主要的碼頭結構形式,其中闆樁牆結構計算又是闆樁碼頭的一個重要内容。
The effect of the significant parameters on the stability of the large diameter cylinder quay of the piled wall type is investigated through numerical calculation.
通過數值計算,研究了結構特征參數對大直徑圓筒樁牆式碼頭穩定性的影響。
"Quay wall"(碼頭岸壁)是港口工程中的專業術語,指沿水域邊緣建造的垂直或傾斜式擋土結構,主要用于船舶停泊、貨物裝卸及防洪護岸。該結構需承受船舶撞擊力、土壓力和水流荷載,通常采用鋼筋混凝土、鋼闆樁或重力式塊體建造。
從工程功能角度,quay wall可分為以下兩類:
現代quay wall設計需綜合考量船舶吃水深度、裝卸設備荷載及地震因素,英國标準BS 6349-1:2018規定了最小設計水深應為船舶最大吃水的1.1倍。荷蘭Deltares研究所的流體力學模型表明,岸壁反射波高與入射波周期呈非線性關系,具體公式可表示為: $$ H_r = H_i cdot left( frac{T}{T_0} right)^{-0.5} $$ 其中$H_r$為反射波高,$H_i$為入射波高,$T$為波浪周期,$T_0$為特征周期參數。
“Quay wall”是港口工程中的專業術語,指碼頭或港口中用于支撐岸線、防止水土流失的垂直或斜坡式結構。以下是詳細解析:
若需進一步了解施工技術或具體案例,可參考工程類文獻或港口設計規範。
