摘要
为了分析某水电站导流隧洞的围岩稳定性,选取影响围岩稳定性的一些主要因素,如岩石质量指标、湿抗压强度、完整性系数、结构面强度系数、地下水渗流量,引入评分机制来评价定性因素对围岩稳定的影响.利用模糊数学原理建立模糊综合评判模型进行分析,获得了与实际情况相一致的结果.
In order to analyze the surrounding rock stability of a diversion tunnel project,some key factors that affect the stability of surrounding rock are selected,and introduce the scoring system to evaluate the impact of qualitative factors on the stability of surrounding rock.According to fuzzy mathematical principle,the fuzzy synthesis assessment method is applied to analyze the stability of surrounding rock;and the results are consistent with the actual case.
