| 摘 要： | 本文根据一致粘弹性模型的概念，引入应变率的影响，将混凝土静态William-Warnke三参数模型改造成一致粘塑性William-Warnke三参数本构模型，并用这个模型对某高拱坝进行了非线性地震响应分析，与线弹性模型和应变率无关的William-Warnke三参数模型的结果进行了比较，初步探讨了应变率对拱坝地震反应的影响。

| Abstract: | According to the concept of consistency viscoplastic constitutive model, a modified consistency viscoplastic William Warnke three-parameter model is developed to take into consideration the strain rate effect. Nonlinear seismic responses of a high arch dam are analyzed with this model, and the calculated results are compared with those of linear elastic model and strain rate-independent William Warnke three-parameter model, the effect of strain rate on seismic response of arch dams is investigated. |
