Embodiment 1

[0050] Taking the curtain grouting of the upper reservoir basin of Huanggou Pumped Storage Power Station in Mudanjiang City, Heilongjiang Province as an example, the grouting data of unit 48 of the main dam of the upper reservoir were selected as the original data for evaluation.

[0051] The established grouting engineering quality grades and the qualitative and quantitative judgment standards of the evaluation indicators are shown in Table 1.

[0052] Table 1 Comprehensive evaluation index and grade value standard of grouting engineering quality

[0053]

[0054]

[0055] After investigation, analysis and processing of the evaluation raw data, the evaluation values ​​of each evaluation index are obtained, as shown in Table 2.

Abstract

The invention provides a grouting quality comprehensive evaluation method based on an analytic hierarchy process and a variable fuzzy set theory, which is characterized by comprising the following steps: selecting first-level indexes and second-level indexes according to industrial standard specifications of grouting engineering construction quality, wherein the first-level indexes are groutability before grouting, design and construction rationality and post-grouting quality, the secondary indexes of the groutability before grouting are rock mass attributes and slurry properties, the secondary indexes of the design and construction rationality are design parameters and construction parameters, and the secondary indexes of the quality after grouting are permeability, compactness and durability; and dividing the grouting project quality grade standards into five grade standards, wherein the grade standards of the grouting project quality grades comprise excellent grade, good grade, medium grade, qualified grade and poor grade. The problems that an existing grouting comprehensive evaluation result is subjective, the requirement for original data is too high, and credibility is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of comprehensive evaluation of grouting quality in water conservancy projects, in particular to a method for comprehensive evaluation of grouting construction quality based on analytic hierarchy process and variable fuzzy set theory. Background technique [0002] Variable fuzzy sets, as a method that can effectively deal with fuzzy and uncertain complex influencing factors, have been applied in many fields. [0003] Chinese patent (CN103177187B) discloses a method for evaluating the health status of highway tunnels based on variable fuzzy set theory. In addition, Fan Guichao et al. realized the fuzzy comprehensive evaluation of grouting quality based on the three indicators of water permeability, rock quality grade, and crack filling rate; Yan Fugen et al. established a grouting efficiency evaluation model based on fuzzy comprehensive evaluation method to comprehensively evaluate the grouting effect; Zhu Yus...
