依托中科炼化离岸式码头工程，通过波浪物理模型试验，对码头桩基墩台底面压强和上托力进行研究。首先，在不同墩台底面相对超高条件下，分析了墩台底面波浪压强作用过程以及分布，对作用的两种压强类型（冲击压强和缓变压强）进行探讨，给出了墩台底面同步平均相对压强与墩台底面相对超高的变化关系。然后，在不同墩台底面相对超高条件下，分析了墩台上托力变化过程，并将最大相对上托力与最大相对同步压强进行比较分析。最后，将上托力试验结果与几种典型方法的计算结果进行比较。相关研究提供了深水离岸式码头的桩基墩台上托力计算依据，可供类似工程借鉴。
依託中科煉化離岸式碼頭工程，通過波浪物理模型試驗，對碼頭樁基墩檯底麵壓彊和上託力進行研究。首先，在不同墩檯底麵相對超高條件下，分析瞭墩檯底麵波浪壓彊作用過程以及分佈，對作用的兩種壓彊類型（遲擊壓彊和緩變壓彊）進行探討，給齣瞭墩檯底麵同步平均相對壓彊與墩檯底麵相對超高的變化關繫。然後，在不同墩檯底麵相對超高條件下，分析瞭墩檯上託力變化過程，併將最大相對上託力與最大相對同步壓彊進行比較分析。最後，將上託力試驗結果與幾種典型方法的計算結果進行比較。相關研究提供瞭深水離岸式碼頭的樁基墩檯上託力計算依據，可供類似工程藉鑒。

Based on the off-shore wharf engineering of the Zhongke Refinery&Petrochemical Company, the uplift wave-pressure and wave-force on pier on piles are researched by wave physical model tests. Firstly, the process and distribution of wave pressure on the undersurface of pier are analyzed under different conditions of relative ultrahigh (height between pier and water surface), the two different types of pressure (pressure of impact and pressure of wave) are discussed, and the relationship between the relative synchronous pressure on the undersurface of pier and relative ultrahigh is proposed. Secondly, the process of uplift wave force on pier is analyzed under different conditions of relative ultrahigh, and is compared with relative pressure. At last, the result of different computing methods of relative uplift wave force on pier is compared with the result of physical model test. The research provides reference about uplift wave force on pier for other off-shore wharf engineering.
