The Large-Scale Direct Shear Test on Gravel Soil with Different Water Content in Badong of Three Gorges Reservoir Region

Abstract:

The high cut slope of reservoir-bank road and city buildings are mostly earth-rock mixture after excavation. The strength behavior of the gravelly soil is important for mechanism of landslide triggering and soil erosion in Badong high cut slope. With the impact of rainfall, the water content of gravel soil increases, and the water table changes, this eventually affects the mechanical properties of gravel soils. Taking high cut slope which formed in the course of relocation in Three Gorges Reservoir as its background, the paper selected the gravel soil of typical high cut slope in Badong new town; and through on-site survey, analysis of geological conditions, indoor large-scale direct shear test, combined with laboratory test results, it discussed the influence of high cut slope gravel soil shear strength parameters by different water content of sample. At the end of this paper, it draws some beneficial conclusions.
