【摘要】 针对地下工程围岩稳定性评价问题,综合考虑影响围岩稳定性的主要因素,提出围岩稳定性综合评价的熵权系数方法,并建立基于熵权系数法的围岩稳定性综合评价模型.基于该模型,对工程实例进行熵权系数法综合评价,得到与可拓学方法和模糊模式识别直接法基本一致的评价结果.结果表明,基于熵权系数法基本原理的围岩稳定性综合评价模型,可以应用于地下工程围岩稳定性的评价,且评价结果可靠、合理.更多还原

【Abstract】 Based on entropy coefficients,a comprehensive evaluation method is proposed to evaluate the surrounding rock stability of underground engineering,which considers the main factors influencing the stability of surrounding rock,and the corresponding model is also established.The stability of practical engineering is evaluated by this model,the results are fundamentally the same as the ones by the method of extenics and the direct method of fuzzy pattern recognition.Therefore the evaluation by this mode is reliable and rational.更多还原
