During the construction of a quay and breakwater project in Israel Ashdod,we study on the loading process of core stone material and propose a kind of new-type stone-loading platform considering the massive core stone (0~1t) requirement and limit construction window of the water throwing of stone water.The girders and steel grating plate are three-dimensional modeled by finite element software Midas Civil.The structural internal force and deformation analysis of the platform are carried out by the British and Europe standards to make sure the safety and reliability of the platform.Actual stone loading and unloading operation on site verifies that the platform can be easily handled and the loading efficiency is high.
