In order to evaluate the treatment effect of grouting for the tunnel and underground engineering geological disasters and reduce the risk of excavation,a comprehensive evaluation method of grouting effect was proposed. Based on grouting capacity analysis,inspection hole analysis,P-Q-t curve analysis and geophysical detecting method,the main influent factors of grouting effect were analyzed and ascertained. Analytic Hierarchy process(AHP) was applied to establish hierarchy model of grouting effect evaluation index system,andthe evaluation factors were quantitative. Fuzzy comprehensive evaluation was used separately to evaluate factors of secondary and primary index. Grouting effect evaluation grade which includes excellence,good,medium and disappointment was established by analyzing evaluated result. The evaluation system and grade standard was adopted to evaluate the treatment effect of Jiangxi Yonglian tunnel F2 fault fracture zone curtain grouting,the evaluation result agrees well with the situation of tunnel excavation. It was preliminarily realized a change from qualitative and empirical to scientific and half quantitative. The research result can be applied to the similar projects.
