涌浪作为库岸滑坡的主要次生灾害,给库区码头、船舶以及水工建筑物带来巨大的安全隐患。高桩码头是目前三峡库区最为常见的码头结构形式之一,船舶撞击力对其在使用阶段的稳定性、安全性具有至关重要的影响。通过水槽模型试验,对滑坡涌浪作用下三峡库区系泊船舶与高桩码头间的撞击力进行研究。试验结果表明:系泊船舶对高桩码头的最大撞击力与涌浪初始波高、水体附加质量等参数有关,与水深无关;而用《港口工程荷载规范》计算得到的船舶撞击力与试验值相比偏小,不利于库区码头的设计安全。结合相关试验数据,提出滑坡涌浪影响下高桩码头船舶撞击力计算公式。
Surge as a major secondary disaster landslides on the bank, the reservoir area terminals, ships and hydraulic structures pose a huge security risk. Piled wharf is one of the most common wharf structures in the Three Gorges Reservoir area. The impact force of the ship has a crucial impact on the stability and safety of the wharf during its use. Through the tank model test, the impact force between the moored ship and the piled wharf in the Three Gorges reservoir area under the effect of the landslide surge is studied. The test results show that the maximum impact force on the piled wharf of the moored vessel is related to the parameters such as the initial wave height of the surge and the added mass of the water body and has nothing to do with the water depth. However, the impact force of the ship calculated from the “Port Engineering Load Code” Than small, is not conducive to the design of the terminal area of ?? security. Combining with the relevant experimental data, the formula for calculating the impact force of ships with piled wharfs under the influence of landslide surge is proposed.
