城市跨线桥梁设计理念及施工方案的简单探讨（Simple discussion on design concept and construction scheme of urban cross line bridge） Simple discussion on city overpass design and construction scheme Abstract: combined with the city road bridge design and construction experience of city overpass design and construction scheme, described from the sub project angle, to probe the related project of. Keywords: To investigate cross line bridge design and construction scheme 0 Introduction The bridge structure design follow the structural safety, applicability, beautiful appearance, convenient construction, and landscape coordination principle. Overpass bridge and viaduct structure design should meet the design requirements and construction clearance, along with the surrounding environment, choosing the reasonable structure of pipeline and engineering geological and hydrogeological conditions. The structure design and strive to speed up construction, achieve reasonable and advanced technology, is conducive to the standardization, mechanized construction, convenient maintenance, maintenance, reduce project cost. The bridge structure should meet the traffic conditions, height requirements and site planning requirements. Strengthen the new technology, new materials and new technology in the project design of bridge structure in application, in order to make the bridge structure simple, economy. The bridge structure should pay attention to the landscape effect. In the selection of structure type, to consider the bridge with the environment, terrain, harmony and unity. Pay attention to the safety of the bridge structure design. The design of bridge structure engineering should take effective measures, ensure the project structure and the safety of road use. To establish the concept of protect the environment. The bridge structure form selection to minimize the construction period and operation period of road damage to the environment. Reflect the comfortable and harmonious requirements. Bridge design
