Abstract

This paper analyzes the slope stress analysis of seepage-stress field under the condition of water lifting of reservoir slope, taking a practical reservoir slope project for example, on the basis of investigation and study of the geological environment, the soil geology model of the reservoir slope is established. On the basis of interaction calculation module of the fluid structure in the software Geo-Studio and Biot theory, finite element method of seepage-stress field coupling is applied to study the variation of stress field of the reservoir slope mainly with strong weathering argillaceous sandstone and marl, on the condition that reservoir water level rise and fall. The maximum principal stress is mainly compressive stress, the tensile stress just distributes near the top of the slope; the minimum principal stress is mainly compressive stress.

Keywords: Fluid-solid coupling, reservoir slope, seepage-stress field, stress analysis, water level lifting.
