洞口二号大桥桥型方案设计比选

Comparison and selection of bridge type scheme design of Dongkou No.2 bridge

综合考虑桥位处地形地貌、地质、路线、施工方法、高压铁塔等因素,对洞口二号大桥提出了三种方案进行桥型比选。详细比较了其中两种可行方案的优缺点,最终采用预应力混凝土连续梁方案,为类似桥梁方案设计提供了参考。

Considering topography,geology,route,construction method,high-voltage tower and other factors,three schemes for bridge type comparison of Dongkou No.2 Bridge were put forward.The advantages and disadvantages of two feasible schemes were compared in detail.The prestressed concrete continuous beam scheme was finally adopted.This project provided a reference for similar bridge scheme design.
