坑道工程围岩稳定性可拓评价方法

Extensics in the application of tunnel rock mass stability assessment of underground tunnel engineering

以可拓论为基础,通过确定围岩稳定性经典域物元、节域物元和计算关联度,建立坑道围岩稳定性多指标可拓数学评判模型。从多个指标综合考虑,得出定量的数值评定结果,从而判断出围岩稳定性类别。该方法把指标结果的不相容性转化为相容性,克服了以往用现实指标与所规定的界限值相比较所引起的判定等级出现不一致的情况,具体工程实例说明,该方法具有很高的可行性。

Based on extensics, a multi-index assessment model for rock mass stability of underground tunnel engineering was established through the ascertainment of the classical field matter-element, segment matter - elements and the calculation of dependent degree. The classification type of rock mass stability was achieved by the quantitative numerical assessment results which considering multi-indexes comprehensively. The method made incompatible multi-index assessment results compatible and avoided the assessment classification＇ s disaecord between the comparison of the indexes and the regulated limit results. A practical engineering example shows it＇ s a feasible new method.
