By the combination of finite element technique with the reliability analysis method, and by the dynamic planning technique, the reliability theory is used in the stubility analysis of complex projects. Thus, the paper integratedly presents the reliability analysis method for complex geotechnic projects. It establishes the mathematical model of dynamic planning. Also, it derives the computation method for the determination of the most dangerous slip lines of complex geotechnic projects and the corresponding minimum reliability index. The paper comprises the corresponding computer programme. Finally, taking a case history, it makes the stability reliability analysis, and obtain beneficial conclusions.
