Expansive soils, known for their significant volume changes due to moisture fluctuations, pose challenges to the stability of soil slopes, particularly in arid and semi-arid regions. This study focuses on model testing to investigate the deformation characteristics of fissured expansive soil slopes subjected to various loading and irrigation conditions. Through laboratory experiments, we simulate real-world scenarios to assess how these soils respond to applied loads and changes in moisture content. The findings reveal critical insights into the effects of fissuring and moisture variation on soil deformation, contributing to a better understanding of slope stability in expansive soils. The results offer valuable data for developing design strategies and mitigation measures to address the challenges associated with expansive soil slopes.
