| 摘 要： | 为探讨大变形较准确的预测方法,在综合分析大变形形成条件的基础上,归纳出岩性条件、应力条件和围岩条件3个方面、8个指标作为影响大变形发生的主要因素。在此基础上,采用模糊综合评判和层次分析相结合的方法,提出了一类新的大变形综合分级预测方法。该方法较全面地考虑了大变形发生的多种影响因素,对各因素的重要性进行了层次分析评价,避免单一判据所带来的局限性。

| Abstract: | To discuss prediction methods of a large deformation and on the basis of analyzing and classifying the developing conditions of a large deformation,three conditions of the rock property,stress state of rock mass and surrounding rock and eight factors are chosen as the indexes of criterion for a large deformation prediction.A new integrated large deformation forecasting method is developed by the fuzzy comprehensive evaluation and the analytic hierarchy process.The method considers many kinds of large deform... |
