瓮马铁路延伸线江界河景区地段线路方案研究

Research on Route Planning of Jiangjiehe Scenic Section of Wengma Railway Extension Line

瓮马铁路延伸线瓮安至遵义段跨越乌江,地质地形条件复杂并穿越江界河景区。为减小不良地质条件对铁路建设及铁路建设对江界河景区的影响,提出了江界河大桥下游330m桥位、经天文绕避江界河大桥、经天文绕避风景区、乌江上游绕避江界河景区共四个方案。综合考虑工程造价、建设工期、地质条件、和对江界河景区影响等因素,推荐江界河大桥下游330m桥位方案。

The Weng'an to Zunyi section of the Wengma Railway extension line crosses the Wujiang River,with complex geological and topographical conditions and crossing the Jiangjie river scenic spot.In order to reduce the influence of bad geological conditions on the railway construction and the railway construction on the Jiangjie river scenic spot,the bridge location of 330m downstream of the Jiangjie river Bridge,through the Ti-anwen town bypassing the Jiangjie river bridge,through the Tianwen town bypassing scenic spot,and through the upper reaches of the Wujiang River bypassing the Jiangjie river are proposed.Considering all factors such as project costs,Construction period,geological condition,impact on Jiangjie river scenic spot,and other factors,the scheme of 330m downstream of the Jiangjie river Bridge is recommended.
