摘要
文中选取10 个指标作为开挖隧道稳定性评价因素,使用组合赋权的方法获取各个指标的权重,其中隧道围岩为影响隧道稳定性的最主要因素.使用模糊物元法对隧道10 个里程段进行开挖隧道稳定性评价,评价结果表明,8 个里程段稳定性为Ⅰ级,2 个里程段为Ⅱ级,情况较好,评价结果与现场结果较为吻合.
Abstract
Ten indexes were selected to evaluate the stability of the excavated tunnel,and the weights of each index were obtained by the meth-od of combination weighting.The surrounding rock was the most important factor affecting the stability of the tunnel.The fuzzy mature-element method is used to evaluate the excavation stability of 10 mileage sections of the tunnel.The evaluation results show that 8 mileage sections are of class I stability and 2 mileage sections are of class II stability,and the evaluation results are in good agreement with the field results.
