摘　　要：为进行隧道及地下工程地质灾害注浆治理的效果评价,降低开挖风险,提出一种注浆效果综合评价方法,基于注浆量分析法、检查孔分析法、P-Q-t曲线法以及地球物理探测法,分析并确定注浆效果的主要影响因素,采用层次分析法,建立注浆效果评价指标体系层次结构模型并量化各评价因子,运用模糊综合评价法对二级和一级指标因素进行评价,通过分析评价结果,建立了优、良、中、差4个反映注浆效果的评价等级标准。采用该评价体系及等级标准对江西永莲隧道F2断层破碎带帷幕注浆的治理效果进行评价,隧道实际开挖情况与评价结果基本吻合,初步实现了注浆效果评价从定性、经验性向科学化和半定量化的转变,研究成果可在今后类似工程中推广应用。In order to evaluate the treatment effect of groutingfor 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, and the 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.
