Comprehensive Evaluation Method of Curved Pipe Jacking Project with Large Diameter and Long Distance Based on Similar Priority Ratio
In order to select the optimal large-diameter and long-distance curve pipe jacking construction scheme,a comprehensive evaluation method of pipe jacking scheme was proposed from four dimensions,including economy,technology,safety and environment,combined with the characteristics of Xinmeng River extension and dredging project.Firstly,based on engineering system theory and hierarchy theory,the evaluation model of pipe jacking scheme decision is established.Secondly,the analytic hierarchy process is used to process the expert opinions to determine the importance and weight coefficient of each element.Finally,the similarity priority matrix is constructed,and the scheme with the highest similarity to the ideal scheme is calculated.The results of the case show that the proposed evaluation method truly and comprehensively reflects the characteristics and connotation of the pipe jacking scheme,and has a certain theoretical guidance and reference for the formulation of practical engineering schemes.
