摘要：
The design of a jointed rock slope angle is an important problem in the design method of rock engineering. The prediction of displacements and deformations of rock slope is an important problem of the rock mechanics in the design of rock slope angle. Based on results of the statistical analysis of a large amount of measured data in slope engineering, the fundamental fuzzy model of displacements of rock slope is established by using the theory of fuzzy probability measures. The formulas of two-dimensional problems are developed and applied to the prediction of the rock mass displacements due to surface mining and the selection of the angles of rock slope. And the selection of slope angles for the open-pit is described. The agreement of the theoretical results with the field measurements shows that our model is satisfactory and the formulae obtained are valid and thus can be effectively used for predicting the displacements due to opencast mining and the slope failure under the influence of groundwater. And the fuzzy system method can be used for reasonable design and selection of the angles of jointed rock slope. © 2004 Elsevier Ltd.
