Problems solved by technology

However, the existing evaluation indicators of the impact image method do not clearly distinguish diseases, which makes it difficult to scientifically evaluate different diseases, so it cannot truly reflect the status of grass-roots diseases, and cannot effectively guide the formulation of maintenance programs

Abstract

The invention discloses a road base disease evaluation method based on an impact mapping method. The method comprises the following steps of parameter setting; data acquiring; data processing and correlation analysis, specifically, selecting road sections with base layer diseases, and analyzing the corresponding relation between the standardized impact response intensity of each road section and the base layer disease category; and then determining the distribution rule and range of indexes, and establishing the corresponding relation between the diseases and the evaluation indexes. Compared with the prior art, the method has the advantages that a parameter acquisition mode and parameters needing to be acquired are improved, the accuracy of detection data is ensured, and the accuracy of adetection result is improved; the influence on the evaluation indexes is avoided as much as possible by adopting process data processing; the corresponding relation between the base layer diseases andthe evaluation indexes is established, the road base layer diseases are judged in a quantitative description mode, or the non-excavation treatment effect is evaluated, the evaluation result is accurate and reliable, reference is achieved, and the evaluation efficiency and the reference value are improved.

Description

technical field [0001] The invention belongs to the field of road disease detection in road engineering technology, and in particular relates to a method for evaluating road base disease based on an impact image method. Background technique [0002] The total mileage of highways built in my country is about 5 million kilometers. Affected by factors such as traffic load, geographical environment and urban development, cracks, deformations and loosening of road bases gradually appear, which have a negative impact on traffic efficiency, driving safety and comfort, and city image. [0003] The common deep-seated diseases of the highway base include: cracks, pumping, voids, subsidence, and insufficient roadbed strength. The deep-seated disease is a recessive disease, which extends upward from the bottom of the base layer to form penetrating cracks, and then develops into a dominant disease of the surface layer, resulting in damage or even loss of road structural performance and ...
