In view of the heightening and thickening levee project which already built, the settlement and deformation on the top of the landside slope of levee and the cracks on the levee were investigated. The finite element method was used to simulated the settlement of the levee. The results show that after heightening and thickening, the thickness of the new filled soil is uneven in the cross-sectional direction of the levee, resulting in a significant difference in the distribution of additional stress and settlement. In addition, the top of the original levee has smaller deformation, while the newly filled levee has larger deformation, which causes uneven settlement on the top of the embankment. The presented results have guiding significance for the settlement and deformation prevention of levee project.
