Abstract

Expansive soil has a significant cracking tendency under arid environmental conditions, leading to numerous engineering hazards. To study the methods of inhibiting cracking of Nanning expansive soil, a desiccation cracking test was conducted on the soil samples improved by biochar and sisal fiber composite. Using image processing to record indicators of soil cracking changes, the influence of biochar and sisal fiber on the expansive soil cracking was investigated. The test results show that sisal fiber, biochar, and sisal fiber + biochar composite all have the potential to inhibit soil crack formation. The sisal fiber + biochar composite demonstrates the most significant improvement. The study results offer valuable reference for the prevention and control of foundation subsidence and slope hazards in expansive soil areas.
