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.
