中文摘要	Magnesia concrete is a kind of expansive concrete used in Chinese hydraulic engineering more and more widely. To evaluate the effects of autogenous expansion on the stresses of arch dams, a simple model of autogenous expansion for Magnesia Concrete in dam engineering is presented. This model is based on three assumptions: 1) the total amount of autogenous expansion of magnesia concrete is related only to the properties of materials and mixing of concrete; 2) the autogenous expansion of magnesia concrete is irreversible due to the irreversibility of hydration reaction of magnesia in the concrete; 3) the autogenous expansion strain rates of magnesia concrete bear a relation between temperature and residual magnesia per unit volume of concrete. The model is verified by some experimental data of autogenous expansion of magnesia concrete and field-measured data of an arch dam in China. Embedded into finite element arch dam simulation software, this model is employed to simulate the effects of autogenous expansion of magnesia concrete in hydraulic engineering.
