The content mainly focuses on the evolutionary processes of the moisture field, stress field, temperature field, and deformation field within loess slopes during instability. It mainly contains the following components: 1. Slope Rainfall Simulation Experiment: Conducted using Fullet rainfall simulation equipment in the Geotechnical Laboratory of Taiyuan University of Technology. This experiment simulates the hydrological response and failure processes of loess slopes under different rainfall intensities and durations. 2. Slope Excavation Centrifugal Simulation Experiment: Carried out on a centrifuge testing machine at Chengdu University of Technology. This experiment simulates the stress redistribution and deformation characteristics of slopes after excavation under a high-gravity field environment. 3. Capillary Water Rise Height Test: Performed using a self-developed capillary water rise height simulation device in the Geotechnical Laboratory of Taiyuan University of Technology. This test measures the migration patterns of capillary water in loess and its impact on toe softening. 4. In-situ Monitoring Test Data: The monitoring site is located at a typical loess slope in Linxian County, Lüliang City, Shanxi Province. By embedding sensor arrays within the slope body, long-term continuous monitoring of deformation, temperature, and other multi-field parameters was conducted to obtain times series data of slope responses under natural environmental conditions.", "ds_quality": "
