重力式码头墙后减压棱体材料选型

重力式码头设计中,抛填块石作为墙后减压棱体会消耗大量的石料。针对近年来北方平原河网区石料匮乏的问题,提出采用废弃混凝土块作为减压棱体填料的设计方案。结合某内河通用泊位工程的设计变更,从工程技术和经济角度综合论证方案的可行性,通过试运营期沉降位移观测验证码头结构稳定性。结果表明,混凝土块作为减压棱体填料可行,可实现资源的循环利用。

Selection of pressure-relief prism in gravity wharf

In the design of gravity wharf,a lot of block stone will be consumed as the pressure-relief prism.In view of the shortage of stone in northern tidal plain river network area in recent years,a design scheme of using the waste concrete block as the pressure-relief prism is proposed.Combining with the design alterations of an inland general cargo berth project,the feasibility of the scheme is demonstrated comprehensively from the engineering technology and economy,and the structural stability of the wharf is verified by the settlement and displacement observation in the trial operation period.The results show that it is feasible to use the concrete block as the pressure-relief prism,which can realize the recycling of resources.
