Analysis of stability for Taizishang slope under condition of atomization rainfall of jet overflows

摘要

Taizishang slope of Qingjiang Reservoir in Huibei is within the range of atomization rainfall. The authors created the finite element model with ANSYS 10.0 and used strength reduction FEM to calculate thesafety coefficient of the slope on conditions with no rain, and theatomization rainfall lasting for 0.2 hours and 0.4 hours. The results show that the atomization rainfall would decrease the stability of the slope, and with rainfalls increasing, the stability would reduce much more.
