中文摘要：

在岩土工程中，粉煤灰混凝土往往受到各种各样的腐蚀，进而使得其蠕变过程非常复杂。根据粉煤灰混凝土受腐蚀作用的特点，通过在马克斯韦尔模型中引进一个随时间变化的刚度系数，建立了其蠕变模型，并在假定腐蚀时间与弹性模量呈线性变化的基础上，得到了粉煤灰混凝土腐蚀过程中的蠕变方程，该方程能够较好地描述粉煤灰混凝土的应变变化速度随着腐蚀时间的持续而不断增大。

英文摘要：

In geotechnicat engineering,the creep process of fly ash concrete is very complicated because of various kinds of corrosion. According to the corrosion characteristics of fly ash concrete,a corrosion creep model was established by introducing a stiffness coefficient varying with time to Maxwell model. Based on assume that the elastic modulus of fly ash concrete varies linearly with corrosion time,a creep equation of fly ash concrete in the process of its corrosion was obtained, which can better describe the process that the strain rate of fly ash concrete increases continuously with corrosion time.
