绿园桥施工图设计
摘要:本设计为绿园桥施工图设计,此桥位于吉林省通江河上。起至桩号为K33+057~K33+183。设计的目的是为了缓解交通压力以及推动经济的发展。通过水文计算设计桥长为126米,经方案的比较认为采用6跨20米结构的预应力混凝土简支板桥较为合适。根据任务书中的要求—,,设计为12块板,桥墩为钻孔灌注桩双柱式桥墩,桥面铺装上层为沥青混凝土,下层为水泥混凝土,经实地调查,该水电站库区地处高山峡谷区,山势挺拔,为较为典型的中高山地形地貌区。。算例内容主要有方案比选、上部结构计算。

Abstract :This is the design for the Lvyuan river. The bridge is located in Jilin province. It plays an important role in the cross-strait economic exchanges and development. The pile number is from K33 + 057 to K33 + 183. Design through the calculation of hydrology bridge is 126 meters long and 6 across 20 meters, comparing the schemes considered that the structure of prestressed concrete simply supporting slab bridge is more appropriate. According to the requirements of the specification, traffic lane width is m, the pavement 2 x0. 5 meters, the design for the 12 boards, bridge pier for double column pier bored piles, the top of the deck surfacing of asphalt concrete, the lower for the cement concrete. Through on-the-spot investigation, the hydropower station reservoir area is located in the mountain valley area, mountain tall and straight, is relatively typical alpine landform in the area , constant lever . Without the requirements of navigation .The example content mainly include scheme selected, the upper structure calculation an
