摘　　要：结合生态治理的要求,在分析国内外生态河堤的发展状况及相关的优缺点的基础上,提出了新型生态河堤,并通过ANSYS有限元软件对生态河堤的承载力及刚度进行有限元分析,对局部河堤结构进行了试验探究,并将有限元结果与试验结果进行对比,吻合情况较好。同时有限元结果也表明结构有较好的承载力、刚度、稳定性以及生态效果等,真正达到了人与自然的关系的和谐。Combined with the requirements of ecological management, the development situation of ecological riverbank at home and abroad is analyzed, and the new type of ecological riverbank is put forward. Then, the beating capacity and stiffness of the ecological riverbank are analyzed through the finite element software ANSYS, and the experiment for the part of the riverbank structure is carried out. At last, the results of ANSYS are compared with experimental results, and the results are very similar. The results of finite element method also show that the structure has good beating capacity, stiffness, stability, ecological effect and so on, really making the relationship between man and nature in harmony.
