Comprehensive Evaluation of Green Bridge Construction Based on a Game Theory–Radar Chart Combination

Abstract

The construction of large bridges requires significant natural resource consumption and causes widespread environmental damage, violating the concept of sustainable development. Therefore, it is necessary to build a comprehensive evaluation system for green construction. This paper took a bridge as a research object to establish a green construction evaluation index system based on GB/T 50640-2010, the “Green Construction Evaluation Standard for Construction Projects”. A combined game theory–radar chart method was adopted to evaluate the level of green construction for five construction schemes. The results were Scheme II > Scheme IV > Scheme III > Scheme I > Scheme V, where Scheme II was the best. The evaluations in this paper were consistent with those obtained by the G1-TOPSIS method; however, a combined-assignment method was used to avoid the one-sidedness of single-assignment, and to make the evaluations more objective.

“…The radar graph analysis method is suitable for the visualized and comprehensive evaluation of multiple variable indicators on a two-dimensional plane [23], which is intuitive and vivid. It is often used in analytical mechanics [24,25], medicine [26][27][28], product quality evaluation [29], and so on. First, its advantage is that it can simultaneously analyze the performance of three or more variables in different dimensions.…”
