摘要/Abstract

摘要： 为准确评价岩溶隧道开挖稳定性,提出一种基于模糊物元的评价方法。首先,分析岩溶隧道开挖稳定性影响因素;然后,建立岩溶隧道开挖稳定性评价指标体系,其中评价指标权重采用层次分析法(AHP)和熵值法综合确定;最后,采用模糊物元的评价方法评价某轨道交通隧道开挖稳定性。结果表明:采用模糊物元对岩溶隧道开挖稳定性的评价结果与实际工程情况相符;该评价方法综合考虑影响开挖稳定性的各因素,并简化评价过程,使评价结果更合理。

Abstract: To solve the problem of Karst tunnel excavation stability, the paper was aimed at working out a new method of excavation stability evaluation. Firstly, the influence factors of Karst tunnel excavation stability were identified, and a stability evaluation index system of karst tunnel excavation was established, in which the weights of evaluation indexes were determined by analytic hierarchy process (AHP) and entropy method. Finally, the fuzzy material element evaluation method was used to evaluate the excavation stability of a rail transit tunnel, and the engineering membership data were processed by the normal membership function to solve the problem of data discretization. The results show that the evaluation results of Karst tunnel excavation by fuzzy matter-element conform with the actual engineering conditions, and that the evaluation method improves the rationality of the evaluation by considering the factors that affect the stability of excavation and simplifying the evaluation process.

Key words: Karst tunnel, tunnel excavation, fuzzy matter-element, evaluation stability, level of evaluation
