| Abstract: | Through orthogonal design,combined with strength reduction method FLAC finite difference program and mathematical statistical analysis method,various stabilizing factors of Quankou red clay cutting slope in Wuhan-Guangzhou Passenger Dedicated Line,such as cohesion,inner friction angle,density of sliding mass,ground water level,slope ratio and dilation angle are separately analyzed and then evaluated using extreme difference method.The results show that the sensitivity of these stabilizing factors are cohesion cslope ratio minner friction angle φdensity of sliding mass ρground water level hdilation angle ψ. |
