摘　　要：强度储备有限元法在工程结构特别是水利工程和岩土工程的整体稳定安全系数求解中得到了愈来愈广泛的应用,但在采用强度储备有限元法进行工程结构整体稳定安全系数求解的计算过程中,存在着耗时多且精度低的问题.为此,基于强度储备法基本理论及ABAQUS软件平台,提出了强度储备安全系数的精确自动求解方法,编制了SCAC程序并进行了工程实例应用.实例应用结果表明,本文所开发的SCAC程序不仅可以极大程度地缩短分析时间,还可实现任意精度强度储备安全系数的全自动计算.Strength reserve FEM is widely used in the calculation of overall stability safety coefficients of engineering structures such as hydraulic structure and geotechnical engineering.In the process of the calculation of overall stability safety coefficients by taking use of safe reserve FEM,the time consuming is always very high,and the accuracy of the strength reserve safety coefficients is always low.In this paper,the method of accurate auto-calculation of strength reserve safety coefficients is presented based on the basic theory of strength reserve method and the platform of ABAQUS software;and then the program of strength reserve safe coefficient＇s auto-calculation（SCAC） is developed and applied to a real project of gravity dam.The results of application show that the SCAC can not only reduce much time for analyzing overall stability,but also can auto calculate the strength reserve safe coefficients with any accuracy.
