Abstract
In view of the particular geological environment in the water-level-fluctuation zone of Three Gorges Reservoir, and on the basis of the systematic analysis of the forces acted on the slope, and the influence of water level fluctuation on the slope stability along reservoir area, this paper studies the effect of the cyclic water pressures on the deformation characteristics of rock, and puts forward the loading system for ten typical design conditions including dry season (natural state), rainy season (rainstorm or rain for a long period of time), dry season + reservoir level (175 m), rainy season + reservoir level (175 m ) + earthquake, rainy season+ earthquake, dry season + reservoir level (175 m) + earthquake, rainy season + reservoir level (175 m) + earthquake, dry season + reservoir level lowered from 175 m to 145 m, rainy seasons+ reservoir level lowered from 175 m to 145 m. A comprehensive analytical evaluation system of the slope stability in the water-level-fluctuating zone of Three Gorges Reservoir Area is proposed on the basis of the static limit-equilibrium method. The research results can serve as the foundation for the analytical evaluation method of the stability of the geological environment in the water-level-fluctuation zone of Three Gorges Reservoir and to constitute the engineering design plan for slope stability control in the reservoir area.
