Abstract

Firstly, based on the model of "Driving force-State-Response" (DSR), take the construction parameters as the driving force indicators, the construction progress as the state indicators, and the construction progress enhancement measures as the response indicators, and construct the construction progress system of the frame bridge crossing the existing railroad line; secondly, take the driving force indicators and response indicators as the object of analysis, and combine the C-OWA operator method and CRITIC method to construct the complex network model. Secondly, taking the driving force indicators and response indicators as the analysis object, combining the C-OWA operator method and CRITIC method to construct a complex network model, determining the importance of the driving force and response elements' own nodes, the intensity of the influence between the nodes and the comprehensive importance of the nodes in turn, and determining the key influencing factors of the construction progress of the frame bridge crossing the existing railroad line project; finally, taking the empirical analysis of the construction progress of a frame bridge crossing the established railroad line project, and analyzing the results of the study.
