Abstract

In order to better adjust to the construction of expressways, this paper analyzes the characteristics of expressways in Yunnan Province and the reasons for the over-budget of some expressways during the 13th Five-Year Plan period. Based on the principle of risk classification, the probability of occurrence and loss caused by the super probability are taken as the important basis of risk classification, and the product of the two is taken as the risk classification factor. The actual operation also adopts the ranking of the occurrence probability of over-budget event and the loss caused by the previous event through the list rating and takes corresponding control measures according to different risk levels, so as to provide reference for the management and control of over-budget risk of engineering construction.
