Abstract：There are some obvious errors and incompleteness in the existing(available) dimensioning concept of GTC flexible slope stabilization systems made of high-strength steel wire mesh in combination with anchor bolt. First，the forces on the mesh resulting from partial instabilities are treated as two independent forces that can¢t be mathematically determined because only one equilibrium equation for them can be formulated. One of the two forces has to be artificially assumed. Second，the longitudinal tensile force of the mesh is assumed as only transmitting to the upper nail；that is，the ability of the GTC flexible system transmitting force all around is neglected. The force concentration degree of the mesh at the upper nail is overestimated；and the dimensioning results are too conservative. Third，the existing concept doesn¢t consider the determination of the lowest force against pull-out of nail. In view of this situation，based on the action mode，the Mohr-Coulomb criterion and the limit equilibrium principle，the concepts of the GTC system are corrected and perfected. Furthermore，the safety checking requirements and the methods to determine the bearing resistance of the systems are established；and the methods to determine the anchoring requirement under different conditions are put forward. So the dimensioning concept and method of the flexible slope stabilization system are perfected.
