The study of artificial slope stability has been a key item of geological engineering projects． Though more evaluation methods are available，result of stability evaluation simulation does not explain the actual prob- lem owing to the diversified geological engineering factors and complexity． The author made a detailed study based on surveys of large amount of geological engineering research on Donggang Power Plant slope project，dis- cussed the comprehensive factors influencing the project，and gave analytical calculation and evaluation to the improved response surface of the slope project． The study result shows that the slope is stable，which can pro- vide scientific basis for designing the slope．
