摘要
采用混凝土非线性本构模型和破坏准则，对３００ｍ级的高拱坝在静力荷载和地震荷载联合作用下的响应进行了线性、非线性对比分析．算例分析表明，对于３００ｍ级的高拱坝，地震荷载会进一步加剧混凝土的开裂，增大压应力，使其安全储备大大降低。拱坝材料非线性的影响不可忽视．
The static-dynamic cracking effects on the dynamic response of a 300 meters high arch dams is carried out based on the nonlinear concrete constitutive relations and failure criteria. Comparison with the corresponding linear analysis shows that, for 300 meters high arch dam, earthquake excitation can further make concrete cracking, intensify compressive stresses, and reduce safety potentialities. The effect of nonlinearity of concrete can not be ignored.
