    APPLICATION OF CLOUD MODEL TO ENGINEERING GEOLOGY CLASSIFICATION OF SURROUNDING ROCK MASS OF TUNNEL

    • 摘要: 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。

       

      Abstract: This paper applies the cloud model theory to engineering geology classification of the surrounding rock mass of tunnel. It calculates the cloud model membership degrees via instituting multi-level quantitative system and assessment level standards of the surrounding rock mass. It then determines the engineering geology classification of the surrounding rock mass by combining qualitative assessment with quantitative classifying results. Through engineering practices, it is shown that the cloud model theory unifies the ambiguity and randomness associated with the conventional surrounding rock mass classification. Its results are compared with the results that are jointly determined by several geological engineers. This comparison shows that the results of rock mass classification are identical in 14 sections among the total 15 sections. The new method has high accuracy and can be reasonably practicable for the classification of the surrounding rock mass of tunnel.
