The structure of the upper part of the south water diversion bridge is 3x40m prestressed concrete continuous box girder with a length of 128 meters. The lower structure bridge pier adopts the column block, the diameter of the column diameter is 1.6 m, the foundation is based on the bored pile foundation, the pile diameter is 1.8m and the transverse total is 8. The abutment platform adopts the pillar type, bored pile foundation, 1.6m。 Zheng is the connection of zhengzhou and xingyang road, one of the important channels of street.Plays an important role in the transport network, to promote various counties and cities along the economic and technical exchanges and play an important role in tourism development, is along the region's economic lifeline, the capacity of economic development along the great influence and resource utilization, has a pivotal position in the regional economic development, a great influence on the development and construction of the national economy。 In this paper, the zheng road bridge project feasibility was studied, including the necessity of project construction, regional traffic analysis and prediction, construction conditions, technical standards, scheme selection, the upper structure calculation, the respect such as investment estimation are studied, the main contents are as follows: (1) the investigation of zhongyuan district near the road network distribution, zheng zheng road along the route of economic, social status, demonstrates the feasibility of the project construction, the necessity and urgency。 (2) the collection of data and related economic and social development planning, along with basic data, detailed according to zhengzhou city planning department toAbstract III zheng road (the west fourth ring to around) section of the road and pipeline planning, determine the objective of the construction scale and technical standards。 (3) through fully solicit the opinions of the relevant units, experts, put forward the construction scheme of different, in such aspects as economy, technology, respectively, for its economic rationality, feasibility and practical engineering, analysis, finally put forward recommendations。 (4) determine the route to the main control points, pavement structure form and main structure。 (5) the upper structure box girder is calculated。 (6) according to the model number of each structure, preparation of investment estimation。 Key words: Cross channel bridge；construction scheme；Box girder calculation； Investment estimation目录 1 目 录 摘要..I AbstractII 目 录...... 1 1 绪论.......1 1.1 选题的背景和意义......1 1.2 国内外可行性研究状况.......2 1.3 项目建设的必要性......4 1.4 本文主要研究内容......5 2 经济社会和交通运输发展现状及规划....7 2.1 研究区域概况.....7 2.2 项目影响区域经济社会现状及发展.....7 2.3 项目影响区域交通运输现状及发展...10 3 道路现状评价、规划及技术标准..14 3.1 道路现状及规划14 3.2 交通量....16 3.3 技术标准18 4 建设方案..... 20 4.1 建设条件...20 4.2 建设项目起终点论证27 4.3 建设方案概况...27 5 大桥上部结构 40m 箱梁计算50 5.1 计算依据及基础资料50 5.2 40m 箱梁计算....52 5.3 结论.72 6 投资估算..... 73目录 2 6.1 投资估算..73 6.2 资金筹措..77 7 结论及建议........78 7.1 主要结论...78 7.2 建议..78
