甘泉洛河大桥特殊水文与多线曲线桥设计

甘泉洛河大桥是包西线上控制工期及线路方案的重点桥渡,该桥是一座与水流斜交角度较小的多线桥。通过桥渡水工模型试验,对桥址处的特殊水文进行了分析,根据分析结果确定了特殊多线桥曲线布置的方法。

Special Hydrology and Multi-line Curved Bridge Design of Luohe Bridge

Luohe Bridge, which control the project schedule and the line crossing of Baotou-Xi＇an railway, is a muhi-line bridge that has a small skew angle with the water flow. On the basis of experimenting with the bridge crossing hydraulic model, this paper analyzes the special hydrology of the bridge. Based on the outcome of the analysis, this paper introduces the curve layout of the special multi-line bridges.
