摘要: 为对运营隧道注浆堵漏效果进行更客观、全面的评价,克服现有评价方法的不足,提出一种基于灰色关联度的模糊综合评价方法,依据注浆施工流程,从注浆过程控制、注浆结束控制条件、注浆检测及注浆可靠度4 个方面建立2 级3 层的注浆效果评价体系,对运营隧道注浆堵漏工程进行注浆效果评价。结合贵阳地铁隧道注浆堵漏工程,选取11 个二级指标建立评价体系,进行注浆效果评价。为简化计算,各指标量化采用符合工程条件的注浆孔数在总注浆孔数中的占比进行划分,逆向运用灰色关联度法构造初始矩阵,并结合层次分析法和模糊综合评价原理得出注浆效果评价为优的结论。经过后续跟踪监测结果,验证了该评价方法在隧道注浆堵漏效果评价中的可行性。

Abstract: A fuzzy comprehensive evaluation method based on grey relation analysis(GRA) is proposed to carry out objective and comprehensive evaluation on the grouting sealing effect of the operating tunnel and overcome the shortcomings of the existing evaluation methods. A two-level and three-layer grouting effect evaluation system is established from the aspects of grouting process control, grouting completion control conditions, grouting detection and grouting reliability, so as to evaluate the grouting sealing effect of the operation tunnel. An evaluation system based on 11 secondary indices selected from the grouting sealing project of Guiyang Metro tunnel is established to evaluate the grouting effect. In order to simplify the calculation, each index is quantified and divided according to the proportion of grouting holes that meet the engineering conditions in the total number of grouting holes, the initial matrix is constructed by using the GRA method in reverse, and the conclusion that the grouting effect evaluation is good is obtained by using the analytic hierarchy process and the fuzzy comprehensive evaluation principle. The follow-up monitoring results verify the feasibility of the system method in tunnel grouting sealing effect evaluation.

Key words: operating tunnel, grouting behind lining, sealing effect, grey relation analysis(GRA), fuzzy comprehensive evaluation
