Abstract

To investigate the impact of freeze-thaw cycles on the stability of basalt slopes in high-altitude mountainous regions, the strength reduction method was combined with Ansys software. Leveraging Ansys’ robust modeling capabilities, a plane failure slope finite element model was established. Numerical simulations were conducted on basalt slopes subjected to varying freeze-thaw cycles. Slope instability and failure were comprehensively assessed based on finite element calculation divergence, the formation of a continuous plastic zone from the slope base to the crest, and abrupt displacement changes at characteristic locations. The slope stability coefficient was analyzed and determined. Results indicate that the stability coefficient of slopes decreases significantly with increasing freeze-thaw cycles. Furthermore, slopes subjected to freeze-thaw cycles exhibit greater maximum displacement during failure compared to unfrozen slopes. These findings provide valuable reference for analyzing factors influencing slope stability.
