大桥施工对内河航道通航条件的影响

摘要

针对大桥施工对内河航道通航条件的影响问题,以武汉江汉六桥大桥施工为例,结合工程局部河段河床演变及航道变化情况,分析研究不同设计代表船型的通航限制条件,探讨不同施工阶段大桥施工对船舶通航的影响,并提出相应的航道安全保障措施,确保大桥施工期航道畅通与通航安全.%To counter the problem of influences of bridge construction on inland waterway navigation conditions,taking Wuhan Jianghan bridge construction for example and considering the bed evolution and channel variation of the engineering river section,we analyze the ship navigation restrictions for different design ship types and study the effect of different construction stages on the ship navigation,and put forward corresponding safetyguaranntee measures for the channel.
