Determining method for road disease cause detection sequence

Abstract

The invention discloses a determining method for a road disease cause detection sequence. The determining method includes the following steps: (1), according to statistics of previous maintenance engineering materials, creating a disease cause occurrence probability matrix A corresponding to disease phenomena; (2), according to the statistics of the previous maintenance engineering materials, creating a probability matrix B of the disease phenomena caused by disease causes; (3), according to the statistics of the previous maintenance engineering materials, creating a normalization vector h; (4), according to spot technical detection, creating a disease phenomenon generation vector w; (5), calculating a disease cause distribution probability p; (6), according to the disease cause distribution probability, determining the disease cause detection sequence. According to the determining method, contributions of occurred disease phenomena to the road disease causes and influences of non-occurred disease phenomena on the road disease causes are comprehensively considered during determining of the disease cause distribution probability, so that calculation process is scientific and reasonable, calculation results are reliable, and detection of the disease causes can be guided scientifically.

Description

technical field [0001] The invention relates to a method for determining the detection sequence of road disease causes, which belongs to road maintenance technology. Background technique [0002] As of the end of 2012, the total mileage of expressways in my country has exceeded 96,000 kilometers. If the maintenance of 96,000 kilometers of expressways is completed within ten years, the annual maintenance mileage will reach 9,600 kilometers. The maintenance needs are huge. The emergence of road surface diseases not only affects driving comfort, but also threatens driving safety. Timely and effective maintenance of roads can not only maintain a good service level, but also delay or even prevent the occurrence of other diseases, thereby prolonging the service life to a certain extent, and obtaining good economic and social benefits. [0003] At present, when road maintenance is carried out, the disease phenomenon is investigated, and then the performance of the road surface is ...

Problems solved by technology

According to the distribution probability of disease causes determined by this method, only each disease phenomenon is considered separately, and the relationship between disease phenomena and the impact of no disease phenomenon on the cause of disease on the road are not taken into account. Therefore, the final distribution probability It is not accurate, and the sorting of the inspection items based on this inaccurate probability is likely to put the most likely cause of the disease at the end for inspection, which increases the workload of inspection and reduces work efficiency
