Because the highway temporarily covers large areas, this article proposes fuzzy comprehensive evaluation method to evaluate the suitability of the reclamation soil in the highway dumping site. According to the impact factors of the land reclamation and the field survey, combining with the principle of fuzzy mathematics, we chose eleven influence factors, including weather conditions, soil physical properties, and soil chemical properties as evaluation factors. In this paper, we regarded nine dumping sites in Chengdu-Chongqing Expressway double-track (Chongqing section) project as samples to make the fuzzy comprehensive evaluation. The results indicate that the reclamation soil suitability in Chengdu-Chongqing Expressway double-track (Chongqing section) dumping sites is relatively good. It provides a useful reference value for the reclamation soil suitability evaluation of the national highway dumping sites.
