毕业设计2(×32)预应力混凝土梁桥.doc

摘 要 如今,预应力混凝土被广泛的使用于各种中小跨度的桥梁中, 根据＂安全,功能,经济,美观＂的原则, 预应力混凝土简支T形梁桥更具有竞争力,反映在工程造价比较低,施工工期短,施工技术成熟等方面。大量采用预应力混凝土将是未来桥梁发展的趋势。 本文以DK1154+435中桥施工项目为例，结合实际情况，对项目的各分部分项工程施工方案进行了详细设计。编制时对项目管理机构设置、施工准备、主要分部分项工程施工方法、工程质量保证措施、安全及文明施工措施、施工现场管理措施等诸多因素尽可能充分考虑，突出科学性、适用性及针对性，是确保优质、低耗、安全、文明、高速完成全部施工任务的重要经济技术文件。 关键词：预应力混凝土 施工 组织设计 预算 Abstract Nowadays, prestressed concrete has been widely used in a variety of small and medium-span bridges. According to the principle of safe, functional, economic, aesthetic, prestressed concrete T-beam bridge is more competitive, reflected in the project cost more low, short construction period, construction technology is mature and so on. Extensive use of prestressed concrete bridge will be the future trend. This paper to DK1154+435 new culvert construction project as an example, combining the actual situation of the project, the partial construction scheme for the detailed design. Prepare to project management organization setup, construction preparation, the main sub-segment of the construction methods, quality assurance measures, safety and civilized construction measures, construction site management measures as fully as possible factors into consideration, outstanding scientific, applicability and pertinence, is to ensure high-quality, low cost, safe, civilized, high-speed completion of all the important task of economic construction technical documents.
