Study to Catastrophe Mechanism of Bedding Rock Slope Burst

Abstract:

Bedding rock slope stability is classic problem of its formation mechanism, and with mechanical means to study the breeding and instability model is one of the important means, Based on summarizing and inducting returns of former researcher, this paper stated that the mechanical model of two-dimensional space may be crossbar bend beam model and of three-dimensional space maybe plate or shell model. Crossbar bend beam catastrophe model of common and multi-load was built. The formulas of burst instable and limit length of bedding rock slope were gained. For example Bawangshan and a special slope near 318 national highway as typical burst slope, their burst and limit length were solved, and the result was proved to be correct and rationality by contrasting with calculation result of other researcher or the actual scene investigate.
