Study on the Predominant Outward Joints Influence on the Stability of High Slope

Article Preview

Abstract:

The advantage outward joints connectivity rate (CR) which extend along the slope plays an important role to overall stability of the high rock slope, but less research on it has been done. In order to research the 180m high rock slope at water inlet of Wudongde hydropower station at Jinsha River, qualitative and quantitative analysis methods have been used. Based on the statistics of the outward joints CR which extend along the slope, and the weighted average parameters of the “bottom sliding surface” combined with the rock bridge, the stability factor of slope has been calculated by rigid body limit equilibrium method. According to the CR sensitivity analysis and calculation, the effect degrees of the joint connectivity rate to the slope stability, and the effect degrees of the bandwidth selection to the CR and stability factors in the bandwidth projection method of linear CR have been demonstrated in paper.
