摘要
高桩结构是码头工程普遍采用的一种结构形式,多年来,码头上部结构耐久性受到挑战,对新型的整体拼装双向预应力板结构进行了模型试验研究,结果显示所提出的设计方案、施工工艺和方法是可行和可靠的,并提出了混凝土结构模型试验的相似准则,从而可根据模型试验所得的荷载能力来估算原型结构荷载能力的方法。
Platform standing on pile foundation is a type of structure used extensively in harbor engineering.Recently,in many years,the beam-slab type of its upper structure still has no advanced progress.In this paper,a new type of concrete platform,prefabricated small slab units of one platform section make up together in site by prestressed steel bars in two directions,is studied by model structure tests.The results show that the design idea and the construction technology and method of the structure are feasible and reliable.In this paper,the similarity criteria of the concrete structure model test is proposed,so the bearing capability of the concrete structures obtained in model tests can be used to estimate the bearing capability in prototype.
