模糊数学围岩分类方法及其在隧道中的应用

Fuzzy Theory Application in Surrounding Rock Classification and in Highway Tunnel

在综合考虑多因素围岩分类法的基础上,引入模糊理论,结合公路隧道特定围岩地质条件的岩体块度、强度、软化系数等多个影响因素,建立围岩模糊分类模型。计算各影响因素的隶属度,按照最大隶属度原则定量判定围岩类别。并将模糊数学围岩分类方法应用于南京老山隧道工程建设中。

The surrounding rock of highway tunnel is mainly classified with the experience method now. Under the special geological condition, it is disadvantage for design and construction management of highway tunnel. Based on the combination of the multiple factors used in classifying the surrounding rock ,the fuzzy theory to build the surrounding rock classification model was introduced and the ambiguity of each factors was calculated. The surrounding rock classification according to the max ambiguity, together with the special geological condition of the highway tunnel was determined.
