新型码头结构在我国港口工程中的应用

New Types of Wharf Structures Applied in Port Engineering

对我国近年出现的几种新型码头结构的研究进行了综述和分析。其中,遮帘式板桩码头结构减小了作用于前板桩上的土压力,使板桩码头在大水深情况下得以应用;双排大管桩码头结构使大管桩较高的轴向承载力和抗弯强度得到充分发挥;架空直立式码头解决了内河大水位差情况下建造码头的难题;椭圆型沉箱的应用避免了采用2个圆沉箱产生前后不均匀沉降的技术难题。最后,对上述新型结构的应用进行了总结。

This paper reviews several new kinds of wharf structures coming out in the recent years. A type of covering-sheet pile wharf reduces the earth pressure acting in front of piles, which can be used in deep water situations; double-rowed large pipe pile wharf gives full play of the large pipe piles to endure higher axial strength and bending strength. Wharf with a platform adjustable in the height helps solve the problem of constructing wharf in rivers of large water level fluctuation; The application of ellipse caisson avoids unbalanced settlement which is induced in using two circular caissons. Finally, the applications for new types of wharf structures are summarized.
