| 摘 要： | 基于长江中游沿岸地质环境条件及过江大桥场地建设基本要求,优选地形地貌、工程地质条件及区域稳定性3个评价因素,运用层次分析法开展长江中游沿岸过江大桥工程场地建设适宜性评价,将长江中游沿岸过江大桥工程分为适宜开发岸线、较适宜开发岸线、一般适宜开发岸线及非优先开发岸线4个等级。长江中游沿岸地区以较适宜开发岸线和一般适宜开发岸线为主,长度分别为625.19 km和598.99 km,分别占岸线总长度的31.35%和30.04%。针对长江中游不同等级岸线的地质特征,提出了相应的地学建议,为长江中游沿岸过江大桥优化选址提供地学指导,进一步促进长江经济带国土资源空间规划与岸线资源保护利用工作的开展。

| 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. |
