The prevention and treatment of expansive soil is a global issue that demands attention. Despite its significance, there is currently a lack of comprehensive technological platforms for the online assessment and rehabilitation of expansive soil slopes. To address this deficiency, our study undertakes a multifaceted approach by constructing a mathematical model and developing real-time data acquisition technology for online assessment. Additionally, we have devised pixel-level, feature-level, and decision-level data fusion technologies to enhance accuracy and effectiveness. In our research, we propose a dynamic assessment and early warning algorithm specifically tailored for the health evaluation of expansive soil slopes. This algorithm facilitates real-time assessment, enabling the identification of three distinct statuses: "healthy", "sub-healthy", and "hidden danger". Furthermore, it provides early warnings for "unhealthy" conditions, ensuring proactive intervention. Accompanying this algorithm, we have implemented reinforcement measures focusing on "external isolation and internal drainage". By doing so, we aim to mitigate the risks associated with expansive soil, thus enhancing the stability and safety of slopes. Another vital aspect of our work involves establishing a comprehensive technological platform covering the entire chain of expansive soil slope prevention and control. This platform encompasses information acquisition and fusion, dynamic health assessment, early warning, as well as repair and reinforcement. By integrating these components, we have significantly elevated the standard of expansive soil slope prevention and control. To verify the effectiveness of our platform, we conducted experiments at the Songgang Wharf, which serves as the head of the South-to-North Water Diversion Project canal. The data collected by our platform proved to be comprehensive and well-fused, providing valuable insights into the actual conditions of the slope. Remarkably, our platform successfully generated 2203 sets of online assessment and early warning data that corresponded well with the real-world situation, thus demonstrating the feasibility and reliability of our algorithm. Furthermore, we implemented rehabilitation and reinforcement measures on the slope, resulting in noticeable reductions in soil moisture and seepage pressure. These positive outcomes suggest that our approach holds great potential for widespread application and can contribute significantly to the field of expansive soil slope management. In conclusion, our study has tackled the global challenge of expansive soil prevention and treatment by developing a comprehensive technological platform and implementing innovative assessment algorithms and reinforcement measures. Through rigorous experimentation, we have demonstrated the feasibility and effectiveness of our approach, which holds promise for widespread application and improved slope stability management.
