Abstract
In this study, we investigate a new design of interlocking revetment that is constructed by precast hollow concrete blocks. The defense structure is to protect the estuary from complex water actions at a river mouth in Vietnam. The hollow concrete block of the structure is designed to be hollow inside for material saving and construction efficiency. Then, the block will be filled by sand onsite. However, the structure performance under the effects of external loads should be investigated since its design is the first time of implementation in coastline protecting system in Vietnam. The block is modeled in ANSYS 18.0 for the calculation of deformation and stresses induced by the action of wave on the block surfaces. The conventional finite element method is used for solving the unknowns of studied models. The investigated results are the displacements of the hollow concrete block in various directions and the equivalent von-Mises stress generated within the structure. The calculation also shows that there are some sharp points of the structure experiencing stress singularity, which should be considered in design.
