Abstract

The invention discloses a tunnel gushing risk grade fuzzy prediction method based on a comprehensive advanced geological prediction technology, and the method comprises the steps: 1, building a tunnelgushing risk grade evaluation index system, and building a tunnel gushing risk grade standard and a quantitative judgment standard of each evaluation index; 2, establishing a tunnel gushing risk fuzzy evaluation model; 3, taking a detection result of a comprehensive advanced geological prediction technology of a certain section in front of the tunnel face as an input value; repeating the step 1,substituting each value into the tunnel gushing risk fuzzy evaluation model in the step 2 to obtain a tunnel gushing risk grade prediction model, and taking the gushing risk grade of a certain sectionin front of the tunnel face obtained by the model as a gushing risk grade of a certain range in front of the tunnel face. By adopting the method provided by the invention, the gushing risk grade prediction problem in front of the tunnel face is solved according to the gushing risk grade evaluation result of the tunnel face and the comprehensive advanced geological prediction technology.

Description

【Technical field】 [0001] The invention belongs to the technical field of tunnel engineering evaluation, and in particular relates to a fuzzy prediction method for tunnel surge risk levels based on comprehensive advanced geological prediction technology. 【Background technique】 [0002] Due to the complex geological conditions, active geological structures, and diverse rock and soil types in mountainous areas, the impact of geological disasters on tunnel construction is prominent, especially outburst disasters, which seriously affect the safety of life and property of construction workers and the normal progress of tunnel construction. Therefore, evaluating the risk level of the tunnel face surge and predicting the risk level of the tunnel face surge has become a key technology in tunnel construction. [0003] In recent years, with the rapid development of advanced geological prediction technology, TSP, geological radar method, transient electromagnetic method, advanced drilli...
