汉巴南铁路嘉陵江桥址方案研究

Study on Jialing River Bridge Site Scheme of Han Ba Nan Railway

汉巴南铁路在南充市境内需跨越嘉陵江,嘉陵江桥址方案的选择直接影响睦坝站至仪陇站间的线位。桥址的选择要充分考虑线路总体走向、地质、水文、地貌、引线条件等因素综合确定。结合汉巴南铁路从可行性研究到初步设计阶段对嘉陵江桥址的方案比选研究,对丘陵山区铁路跨越大江、大河的线路方案比选工作提供借鉴。

Hanzhong-Bazhong-Nanchong railway needs to cross Jialing River in Nanchong,The selection of Jialing River Bridge site directly affects the line from Muba station to Yilong station.The selection of bridge site shall fully consider the overall route,geology,hydrology,landform,lead conditions and other factors.Combined with the scheme comparison and selection study of Jialing River Bridge site from the feasibility study to the preliminary design stage of Han Ba Nan railway,it provides a reference for the comparison and selection of line schemes for railway crossing rivers and rivers in Hilly and mountainous areas.
