本文将云模型理论应用于隧洞围岩工程地质分类,通过建立隧洞围岩分类多级定量指标体系及评价等级标准,计算隧洞围岩云模型隶属度,将定性评价与定量划分成果进行结合,判定隧洞围岩工程地质类别。通过工程实践应用,该方法对围岩分类问题中的模糊性和随机性进行了统一,围岩分类结果与多位地质工程师联合判断结果相比较,在共计15段围岩中有14段相同,具有高的准确度,云模型理论应用于隧洞围岩分类是合理可行的。
In this paper, the cloud model theory is applied to engineering geological classification of tunnel surrounding rock. By establishing multi-level quantitative index system and classification criteria of surrounding rock classification of tunnel, the membership degree of tunnel cloud model is calculated, and the combination of qualitative evaluation and quantitative results is determined Tunnel surrounding rock engineering geological categories. Through the application of engineering practice, this method unifies the fuzziness and randomness in the classification of surrounding rock. Compared with the result of joint judgment of multiple geotechnical engineers, there are 14 sections in the total of 15 sections of surrounding rock, With high accuracy, it is reasonable and feasible to apply cloud model theory to tunnel surrounding rock classification.
