摘要
跨河桥为某水库的配套工程,位于坝址下游2Km处,为连接两岸的永久桥梁。桥梁的修建,使工程区内形成环形交通,提高工程管理的可靠度。桥梁设计满足《防洪标准》要求,桥梁建成后,桥位断面水位壅高使得桥下净空有可能不满足有关要求,同时可能会对第三方合法水事权益产生影响,但不会对河道行洪以及对下游河段的河势造成影响。
River bridge for a reservoir supporting projects,located in the lower reaches of the dam 2Km,to connect the two sides of the permanent bridge.The construction of the bridge,so that the formation of circular traffic within the project area to improve the reliability of project management.Bridge design to meet the "flood control standards" requirements,after the completion of the bridge,the bridge level water level obstruction makes the bridge under the clearance may not meet the requirements,and may have a third party legitimate water rights have an impact,but not on the river flood As well as the river reaches the lower reaches of the river.
