北京动车段转向架检修间维护结构及基础设计

Design of Exterior-protection Construction and Its Foundation of Bogie Repairing Room of Beijing EMU Maintenance and Repairing Depot

研究目的:对砌体维护墙采用带形窗及抗风柱与屋架的连接在设计中应该考虑的问题提出看法,并提供范例,为垃圾填埋场基础设计采用载体桩提供示图,供今后同类建筑结构设计参考。研究方法:综合介绍北京动车段转向架检修间的设计,从而总结概括出此类建筑的若干设计要点。研究结果:在预制柱牛腿与现浇梁的接触面预埋型钢抗剪,使梁与牛腿在同一平面内浇为一体。载体桩可穿过垃圾填筑层,挤密土体,提高桩的承载力。研究结论:采用型钢抗剪是提高现浇与预制接触面抗剪能力的有效措施;抗风柱应将风荷载传到横向水平支撑节点处;复杂地质情况的基础设计应结合具体情况采用不同的基础形式降低工程造价。

Research purposes： The views are expresses on the issues for caution in design of connecting cingulum window and wind resisting column with room＇s roof truss to the enclosure wall and the sketches of cartier piles are presented for design of the foundation of garbage disposal plant for the purpose of providing the references to design of similar building structure.Research methods： Based on the design of bogie repairing room of Beijing EMU Maintenance and Repairing Depot, the key points of design such building are summed up.Research results： The section steel is embedded in the contacting face in- cast beam so as to integrate the beam garbage layer to compact the soil body for with the leg in the equivalent improving the bearing capacity between the prefabricated column＇s leg and plane. The cartier pile can pass through the of the pile.Research condusions：Application of section steel is an effective way to improve the capacity of resisting the shearing force in the contacting face between the prefabricated column＇s leg and in - cast beam. The wind resisting column can transfer the wind load to lateral fulcrum, but the different foundational forms should be adopted to the different situations under complex geological conditions.
