Moreover, 3D discrete element code (3DEC) was used to solve the deformation of the high slope in the modes of mixed discontinuousness and degenerate continuousness. The influence of structural plane on the calculated result was discussed, and the stability of the high slope at inlets after excavation and reinforcement was analyzed by comparison of the calculated results in different calculation modes.

Optimization solution algorithm is the most important in topology optimization.Algorithms fit for discrete structure and continuum structure are all investigated. Thecharacteristic and different using limit of both optimization criteria method andmathematics programming method are all analyzed in this paper. OC algorithm and theseries MMA algorithm based on SIMP approach are deducedand used for the topology optimization problem of continuum structure.

Thecharacteristic and different using limit of both optimization criteria method andmathematics programming method are all analyzed in this paper. OC algorithm and theseries MMA algorithm based on SIMP approach are deducedand used for the topology optimization problem of continuum structure. MMA algorithm hasa bad convergence but it has a high computational efficiency, while GCMMA is excellent onconvergence and stability with bad calculation efficiency.
