SENSITIVITY ANALYSIS OF MULTISTAGE SLOPE STABILITY INFLUENCING FACTORS IN SEISMIC AREAS
To optimize slope design and predict the safety factor of slope stability under seismic loading,this paper considers the effects of soil parameters and slope geometric parameters.It uses orthogonal experiments and range analysis to conduct a sensitivity analysis of factors affecting multi-stage slope stability under seismic loads.The re-sults indicate the sensitivity order as follows:internal friction angle>slope ratio>slope height>cohesion>plat-form width>seismic peak acceleration>density.Additionally,predictive models were developed for each influenc-ing factor in relation to the safety factor of slope stability,showing good predictive performance.The findings provide a reference for evaluating the stability of similar slopes.
