灰色系统理论是用于研究少数据和贫信息的不确定性问题的新方法。为了分析具体边坡工程的边坡稳定性,在简要阐述边坡稳定性方法、介绍灰色系统基本原理和分析不确定性分析方法之间的差异性基础上,通过灰色关联分析的灰色关联度方法,以重庆万梁高速公路边坡工程的稳定状况为参考样本及预测样本,选取影响边坡稳定性的一些主要因素,建立数学模型,讨论了基于灰色关联分析理论的边坡岩体稳定性计算方法及其有效性。结果表明:模型计算与实际情况一致,灰色关联分析理论方法能全面地考虑工程中的信息贫乏和实际边坡问题的非确定性属性,简单易算,同时能较好地预测边坡稳定性。
Gray system theory is a new method for studying the uncertainty of low data and poor information. In order to analyze the slope stability of a specific slope engineering, based on a brief description of the slope stability method and the difference between the basic principles of the gray system and the analysis of the uncertainty analysis methods, the gray relational analysis method Taking the stability condition of the Slope Project in Chongqing Wanliang Expressway as a reference sample and a prediction sample, some main factors affecting the slope stability were selected to establish the mathematical model. The stability calculation of the slope rock mass based on the gray relational analysis theory was discussed Method and its effectiveness. The results show that the model calculation is consistent with the actual situation. The gray relational analysis theory method can comprehensively consider the information deficiency in the project and the non-deterministic property of the actual slope problem, and is easy to calculate and can predict the slope stability.
