The analysis of slope stability and the optimization of support design in high - intensity seismic zones are crucial for ensuring the safety of slope engineering. Under seismic action, the stress state of slope rock - soil mass undergoes drastic changes, which can easily lead to instability. This study comprehensively considers factors such as the characteristics of seismic motion, slope geometry, and rock - soil mass properties. It employs numerical simulation methods to analyze slope stability and identify potential instability regions. Based on this, strategies for the optimization of support design are proposed, including the selection of appropriate support structure forms and parameters to enhance the seismic performance and durability of the support structures. The effectiveness of the design is verified through numerical simulation and field monitoring, providing a scientific basis for slope engineering in seismic zones.
