Geotechnical slope stability analysis is a crucial topic in geotechnical engineering.The traditional Limit Equilibrium method has some flaws and limitations,making it difficult to accurately reflect the real failure state of the slope.It adopts the Finite Element Strength Reduction method to analyze the stability of a jointed rock slope.By continuously reducing the strength parameters of the slope until the model collapses,the safety factor of the slope is calculated and the sliding surface of the slope is determined.It also adopts different stability assessment crite-ria,such as calculation convergence,displacement jump,plastic zone penetration,etc.,to comprehensively evaluate the stability of the slope.The results show that the Finite Element Strength Reduction method can effectively simu-late the failure process of the rock slope,taking into account the complex geometric shape,material nonlinearity,joint fissures and other influencing factors of the slope,improving the accuracy and reliability of the analysis,and providing a reference for the design and construction of slope engineering.
