【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。
[Abstract]:In order to evaluate the effect of grouting treatment of tunnel and underground engineering geological hazard and reduce the risk of excavation, a comprehensive evaluation method of grouting effect is put forward, which is based on grouting quantity analysis method, checking hole analysis method, P-Q-t curve method and geophysical detection method. The main influencing factors of grouting effect are analyzed and determined. The hierarchical structure model of grouting effect evaluation index system is established by AHP, and each evaluation factor is quantified. The second and first grade index factors are evaluated by fuzzy comprehensive evaluation method. Through the analysis of the evaluation results, four evaluation grade standards, excellent, good, medium and poor, are established to reflect the grouting effect. The evaluation system and grade standard are used to evaluate the grouting effect of the curtain grouting in the F _ 2 fault broken zone of Yonglian Tunnel in Jiangxi Province. The actual excavation of the tunnel is basically consistent with the evaluation results, and the change of grouting effect evaluation from qualitative, empirical to scientific and semi-quantitative is realized. The research results can be popularized and applied in similar projects in the future.
