摘要
水电站一般都有永久坝顶公路桥和沟通左右岸的临时交通桥,选用何种架设方式直接关系到工程的安全、工期和成本。本文结合挂治水电站溢流坝段坝顶永久公路桥和下游施工便桥架设所面临的不同施工环境,通过安全经济比较,对分别采用的三种不同安装方式作了论述,为同类水电站提供了借鉴。
Permanent access bridge at dam crest and/or downstream temporary access bridge is usually existed in hydroplant and its erecting method will impact directly the construction safety, duration and cost of the hydroplant. The article mainly discuss three kinds of different installation methods of the access bridge located at the spillway weir crest and downstream of the dam according to different circumstance for the economical and safe purpose in Guazhi hydroplant.
