岳阳城陵矶底梁式全直桩码头物理模型试验设计

Physical Model Test Design of All-vertical-piled Pier with Bottom Beam in Chenglingji of Yueyang

介绍了一种能够满足防洪要求、具有较高的靠泊等级并能够适应较大水位差的新型码头结构。为了研究这种码头结构的受力特性及力在立柱、桩上的分配情况,采用结构模型试验的相似理论,推导了相似指标。在此基础上,选择合适的材料建立模型对岳阳城陵矶新型码头进行缩尺模型试验研究。介绍了模型试验的结构设计和加载方法设计,其土的模拟方法能够为类似模型试验提供参考。

A new kind of pier structure is introduced,which can meet flood control requirements,possess a higher ship berthing level and can be able to adapt to a larger docking water level drop.In order to study the force characteristics acting on the structure and strength distributions on the column and pile,the structural model test similarity theory is used to derive a similarity index.On this basis,the appropriate materials are selected to simulate the new dock for Yueyang Chenglingji scale model experimental research,and the structural design of a model test and design of loading methods are introduced,the simulation method of soil can provide a reference for similar model test.
