الملخص EN
SRM (strength reduction method) with iterative method of PFE (partitioned fnite element) and IBE (interface boundaryelement) is proposed to solve the safety factor of local discontinuous rock mass.
Slope system is divided into several continuous bodies and local discontinuous interface boundaries.
Each block is treated as a partition of the system and contacted by discontinuous joints.
The displacements of blocks are chosen as basic variables and the rigid displacements in the centroid of blocks are chosen as motion variables.
The contact forces on interface boundaries and the rigid displacements to the centroid of each body are chosen as mixed variables and solved iteratively using the interface boundary equations.
Flexibility matrix is formed through PFE according to the contact states of nodal pairs and spring flexibility is used to reflect the influence of weak structural plane so that nonlinear iteration is only limited to the possible contact region.
With cohesion and friction coefficient reduced gradually, the states of all nodal pairs at the open or slip state for the first time are regarded as failure criterion, which can decrease the effect of subjectivity in determining safety factor.
Examples are used to verify the validity of the proposed method.
