[Retracted] Stability Evaluation of Rock Slope in Hydraulic Engineering Based on Improved Support Vector Machine Algorithm

Table 1

The comparison of various limit equilibrium methods [11–13].

Method	Horizontal force	Torque	Conditioning	The slip crack surface form	Methods	Parameter
Swedish law	Y	N	N	Exclude force between bars	Circular arc form	N/A
The simplified Bishop method	Y	N	Y	The interbar shear force is not considered	Circular arc form	N/A
Simplified Janbu method	N	Y	Y	The resultant force between bars is horizontal	Arbitrary shape	Do not use
Morgenstern-Price method	N	N	Y	The force between bars is a function	Arbitrary shape	Calculate
Salma method	N	Y	N	The sides of the sliver also reach the ultimate equilibrium state	Arbitrary shape	Calculate
