Block theoretical engineering analysis software KBTE-2.0

1. Main functional features and interface features of the software

(1) Full space polar projection and analysis: directly display the type of joint cone, the movement mode of joint cone, the stability coefficient and residual sliding force ignoring the cohesive force on the graph;

(2) Complex block shape analysis: no positioning block geometry analysis; Shape analysis of positioning blocks including concave blocks;

(3) Block stability and support force analysis: considering the effects of groundwater, earthquake, external load, etc., block stability coefficient calculation, block support force analysis; Stability analysis of multi-slip surface blocks and complex blocks;

(4) Analysis of the largest mass shape of underground cavern;

(5) Equilibrium region diagram (Londe diagram);

(6) three-dimensional structural plane network simulation considering positioning and random structural plane; Three-dimensional random block geometry search for cavern and slope problems; Statistical analysis of block geometric characteristics (size, average size, buried depth and coverage rate, etc.);

(7) three-dimensional block cutting analysis of slope and cavern rock mass (full space block search), and progressive block instability analysis;

(8) Block reliability analysis considering the random distribution of structural plane mechanical parameters and geometric parameters; Block occurrence probability and block failure probability analysis
