The traditional concrete or ecological slope protection structures cannot satisfy the needs of coastal protection for structural anti-wave,energy dissipation,durability and ecological requirements.Aiming at the characteristics of coastal protection engineering in Mirsarai,Bangladesh,we adopt the concrete block and ecological slope protection structure type through the comparison and selection,and analyze the technical and quality difficulties,problems in typical construction,the stability of the base trough prisms,slope blocks,ecological slope protection and structural drainage.The results show that the stable mass of the foundation and the slope block satisfies the requirements for anti-wave,and can effectively withstand the impact of sea waves during the flood season.Vegetation ecological slope protection uses the root system to reinforce the soil layer,controls the erosion of soil particles and lower materials,and plays a role of ecology and landscape.
