Effect of Compost Soil Treatment on Surficial Slope Stability in Fully Softened Condition
Desiccation cracking occurring in expansive clays during seasonal changes poses a serious threat to the structural integrity of foundations, slopes and retaining walls. Soil treatment with compost additive has been successful in the past in reducing soil cracking due to dessication. The current research study focuses on the effectiveness of compost treatment on slope stability. The fully softened shear strength exhibited by the soil is considered in this analysis to assess the long-term stability of the embankment slope. Bromhead torsional ring shear equipment was utilized in this research to determine the residual strength parameters of the soil. Fully softened shear strength (FSS) soil parameters obtained from laboratory testing are used as input parameters for slope stability analysis using SLOPE/W software. The factor of safety obtained for different scenarios of rainfall events is determined and presented in this research. This study revealed that the compost treatment on surficial soil helped in mitigation of desiccation cracks resulting in a higher factor of safety for the embankment stability.
