The development of underground engineering promotes the development of grouting technology, but due to its particularity, the research of grouting theory lags behind the application requirements of actual engineering, and the evaluation of grouting effect is a weak link in grouting theory. Grouting effect is influenced by many factors with uncertainty and nonlinear characteristics. Four factors, anti-inference method of slurry filling rate, displacement monitoring method, exposure observation method, core method in access hole, were proposed, and the corresponding quantitative indexes were determined. In this study, a novel evaluation model was developed using analytic hierarchy process and ideal point method to study grouting effect in weak and water-rich stratum. The results show that this method is feasible. With its strong operability, the proposed method provides a new means to evaluate grouting effect.
