Abstract:

In order to further improve the maintenance quality of subgrade,the subgrade condition evaluation is analyzed based on the standard method and the analytical hierarchy process,respectively.Then,according to the investigation results of subgrade condition carried out for three typical highways in Guangdong Province,the weight parameters of twenty-one factors and five components are determined via an analytical hierarchy process,and the subgrade condition index of fifteen test sections is calculated.Finally,a comparison is made between the calcula- ted results and the results obtained by the standard method.It is found that,as compared with the standard me- thod,although the analytical hierarchy process basically gives the same results,it is more objective and can reflect the subgrade condition and diseases in highway operation period in detail,which helps to perform subgrade main- tenance engineering more reasonably with clear aims.

Key words: highway operation, subgrade condition evaluation, analytical hierarchy process, subgrade main- tenance
