Stability Analysis for Coupling Hydraulic-Mechanical Unsaturated Deposit Body under Rainfall Infiltration
In view of the deficiency of traditional saturated soil theory analyzing seepage and stability of slope under rainfall infiltration, based on the saturated-unsaturated flow theory, considering the mechanical behavior of slope which strongly coupled with flow behavior, the hydraulic-mechanical coupled finite element method on the case of rainfall induced instability in deposit body in Front of gushui Dam are used. The safety factor is calculated based on stress field obtained from the finite element method, with modified unsaturated Mohr-Coulomb failure criterion. The influences of rainfall duration and rainfall intensity to stability of deposit body are analyzed; the difference between calculated safety factor based on unsaturated flow theory and saturated flow theory is discussed.
