This paper introduces structure options of nibble mound sea wall on soft foundation and a new type of armour block-hexagon multihole block (HMB) and a new method of treatment for soft foundation by using underwater explosion. Construction practice of some projects in China shows that by using this method good effect of treatment and marked economic benefit can be achieved by using this method.展开更多

A method for predicting the ship-ship interactions, based on a non-hydrostatic shallow water flow model, is presented in this paper and is validated by comparing the numerical results with experimental data. The method is subsequently applied to predict the interaction forces acting on a berthed ship due to a passing ship in ports. The influences of the difference of the water depths between the dock and the main channel, the dock geometry, the current and another berthed ship in the dock on the ship-ship interactions are studied. Analysis based on the numerical results is carried out, which is useful for the port design.展开更多
