Abstract
Seawalls have been implemented for coastal protection for centuries. The gravity type vertical seawalls made of plain concrete is the most common one used widely because of its advantages such as competitive construction cost, little maintenance requirement, etc. In this work, a novel three dimensional precast thin-walled concrete block forming seawall has been simulated by using finite element software. Unlike the traditional gravity type seawalls, such as hollow block, is low self-weight structure and can be damaged under exceed load. Therefore, load-bearing capacity of block itself under wave attack is necessarily evaluated. Of course, stability of seawall structure against sliding, overturning or bearing capacity of soil foundation are important factors and should not be overlooked. Theoretical aspects and computational modelling procedures are presented in detail. ABAQUS commercial software is adopted for this study.
