本文引进裂缝深度约束条件，研究了拱坝开裂条件下的体形优化设计问题．结构分析采用超级有限单元法，既能有效控制计算规模又能方便地反映结构开裂的局部特性．对小湾拱坝和溪洛渡拱坝进行的优化设计研究表明，在优化过程中允许开裂并考虑开裂约束条件，可以更好地挖掘拱坝潜力，进一步减小坝体混凝土方量．
In this paper, the constraint of depth of crack is introduced to study the shape optimization design of arch dam under cracking conditions. Structural analysis using super finite element method, both to effectively control the size of the scale and can easily reflect the local characteristics of structural cracking. The optimization design of Xiaowan arch dam and Xiluodu arch dam shows that cracking and cracking constraints are allowed in the optimization process, which can better excavate the potential of arch dam and further reduce the concrete mass of dam.
