【摘要】:水下拋石基床在海岸工程中應(yīng)用廣泛,重錘夯實法為拋石基床的主要密實方法之一。針對水下強夯過程中,夯錘受到水阻力影響,無法準(zhǔn)確測定夯擊能的問題,進行圓臺型夯錘在水中運動特性的試驗研究,采用理論計算、模型試驗及數(shù)值模擬相結(jié)合的方法,通過對比分析,得到確定夯錘水阻力系數(shù)的數(shù)值計算方法,為確定不同形狀的夯錘有效夯擊能提供依據(jù)。
[Abstract]:Underwater riprap bed is widely used in coastal engineering. Heavy hammer ramming method is one of the main compacting methods of the bed. In view of the problem that the tamping hammer is affected by water resistance in the process of underwater dynamic compaction, it is impossible to accurately measure the tamping energy. The experimental study on the motion characteristics of the round type rammer in water is carried out, and the method of combining theoretical calculation, model test and numerical simulation is adopted. Through comparison and analysis, a numerical calculation method for determining the water resistance coefficient of the rammer is obtained, which provides a basis for determining the effective tamping energy of the rammer with different shapes.
