Ground penetrating radar (GPR) is widely used in advanced geological prediction. It is necessary to choose a scientific and effective evaluation method to give a reasonable evaluation of the accuracy of prediction. In this paper, a method based on improved analytic hierarchy process (AHP) and GPR is proposed to evaluate the accuracy of advanced geological prediction. Based on the analysis and induction of the factors that affect the accuracy of GPR prediction, an improved AHP is proposed, in which a new measure of “numerical weight” is added and the principle of maximum membership degree is integrated, and an improved AHP model is established for GPR prediction accuracy classification and evaluation. The engineering application of Xiaobeishan Tunnel of Jie-Hui Highway is taken as a case study, and it is proved that the evaluation indices are easy to obtain and the evaluation results are accurate and reliable. The improved AHP-GPR method can be further used for other tunnel engineering.

基于改进AHP和GPR的先进地质预报精度评估。

探地雷达（GPR）被广泛用于高级地质预测中。有必要选择一种科学有效的评估方法来对预测的准确性进行合理的评估。本文提出了一种基于改进层次分析法（AHP）和GPR的方法来评估高级地质预报的准确性。在分析和归纳影响GPR预测准确性的因素的基础上，提出了一种改进的层次分析法，增加了一种新的“数值权重”度量方法，并结合了最大隶属度的原理，提出了一种改进的层次分析法模型。建立用于GPR预测准确性分类和评估的工具。以捷汇公路小北山隧道的工程应用为例，证明了评价指标容易获得，评价结果准确可靠。改进的AHP-GPR方法可进一步用于其他隧道工程。
