| 摘 要： | 针对岩质边坡的稳定性评价问题,应用粗糙集理论对既有岩质边坡的失稳实例进行分析,采用遗传算法进行约简,抽取评价知识,建立了规则库。采用不精确推理和默认推理方法开发了岩质边坡稳定性评价专家系统,提出了待评对象与规则不完全匹配情况下的近似推理方法,结合工程实例对该系统进行了测试和验证,并与模糊回归方法进行的比较。 |

| Abstract: | To provide the rock slope stability evaluation,this study follows the rough set theory by analyzing slope failure examples.Genetic Algorithms(GA) is introduced to reduce attributes and obtain information to build rule base.Inexact reasoning and default reasoning methods are introduced to develop stability evaluation expert system of rock slope.Approximate reasoning method is used when the engineering attributes cannot match the rules.In order to test the validity of this system,an engineering example is evaluated and the evaluation results are compared with the calculation results obtained from the fuzzy regression approach. |
| Keywords: | rough set slope failure decision table fuzzy regression GA expert system |
