Abstract
This chapter presents a new methodology for rock slope design in karst-prone ground conditions based on integrated karst cave stochastic model-limit equilibrium method. The numerical modeling and optimization design procedure contain a collection of drill core data, karst cave stochastic model generation, stability assessment and bisection method optimization. A code for karst cave stochastic model generation, named KCSMG, is developed. The stability of the rock slope with the karst cave stochastic model is analyzed by combining the KCSMG code and the SLIDE program. This approach is then applied to study the effect of the karst cave on the stability of the open pit slope, and a procedure to optimize the open pit slope angle is presented.
