Abstract

This paper took certain a landslide in Sichuan province as a research object and focused on characteristics of groundwater flow and stability of the landslide with changes of conditions. Three-dimensional conceptual model was established for groundwater flow in the landslide with weak permeable media. Results show that there is good agreement between numerical calculation and observed groundwater table and that relative error of groundwater table calculated from the model is less than 0.13%. During the rising of the river water level, groundwater table in the slope body increases gradually and the landslide stability coefficient changes from rising, then declining to rising. The minimum stability coefficient of the landslide is 3% lower than that of the natural condition. The results can provide stability evaluation and engineering prevention treatment of the landslide with scientific basis.
