软土路基安全性评价专家系统研究

根据软土路基的特点,考虑建模过程的系统全面性、简明科学性、相对独立性及灵活可操作性,选取合理的路基安全性评价指标,用层次分析法确定评价指标的权重矩阵,采用模糊综合评判方法建立软土路基安全性评价分级模型,并建立专家系统,应用专家系统对唐山市滨海大道的路基安全性进行评价。结果表明,此模型和专家系统能很好地反映软土路基的安全性状况,具有合理性和实用性,可供同类工程借鉴。

Research on safety evaluation expert system of soft soil subgrade

According to the characteristics of soft soil subgrade,considered the comprehensiveness,concise scientificalness,relative independence and flexible operability of system during the modeling,selected a reasonable subgrade security evaluation indicate,determined the weight matrix of evaluation indexes with analytic hierarchy process,established safety evaluation classification model of soft soil subgrade with fuzzy comprehensive evaluation method,and established an expert system,used the expert system to evaluate the subgrade security of Binhai avenue in Tangshan.The results show that this model and expert system can well reflect the security status of the soft soil subgrade,it is rational and practical and can be a reference for similar projects.
