Abstract:Based on the analysis of the morphological characteristics, stratigraphic lithology, hydrogeological environmental conditions and geological structure of the soil landslide in the front road of Fushan high-speed railway station in Chengmai County of Hainan Province, the three-dimensional visualization model of the landslide area was established through the stratum module in the GEO5 software, combined with topographic survey, layer structure and stratigraphic classification. On the basis of this model, the authors adopted the slope stability analysis module and Sarma method to conduct numerical simulation research on the slope stability and the position of the sliding surface under two working conditions of natural state and full water state. The simulation results are in agreement with the field survey results, which will provide some theoretical basis for the establishment of reasonable landslide prevention and control measures in the future.
