Abstract:Based on the geological environmental conditions along the middle reaches of Yangtze River and the basic requirements of the bridge site construction, three evaluation factors—topography and landform, regional stability, and engineering geological conditions were chosen in this paper. The authors applied Analytic Hierarchy Process (AHP) to evaluate the construction suitability of the bridge site along the middle reaches of Yangtze River. Four grades as appropriate for development, relatively appropriate for development, generally appropriate for development, and non-priority development, were divided. The bridges in the middle reaches of Yangtze River are mainly areas suitable for development and generally suitable for development, with lengths of 625.19 km and 598.99 km respectively, which account for 31.35% and 30.04% of the total length of the bank line. According to the characteristics of each grade in the middle reaches of Yangtze River, corresponding geological suggestions were put forward. It is expected to provide geological guidance for optimizing the site selection of the bridge along the middle reaches of Yangtze River, and to promote the spatial planning of Yangtze River Economic Zone and the utilization and protection of the bank line.
