A new recognition of stability of the slope of cut

Based on the theories of G-force field and of the mechanics of materials, in combination with practical construction and results from laboratory, to make a detailed study on the stability of the slope of cut, and elicit some new opinions on the mechanism of the stability of the slope of cut and a new warning formula. To draw a conclusion that the slope of cut slides basically on the condition that the residual gravity of rock strata, after balancing the maximum static friction force, exceeds the critical pulling resistance force. Therefore the mechanical characteristics of the slope of cut and the interaction and transfer of the forces can be explained by a formula relevant offered. And there is a qualitative and quantitative analysis for the stability of the slope of cut, practically and effectively.
