【摘要】 该文对混凝土斜拉桥前支点挂篮三种止推方式进行了分析比较,认为选用不同的止推形式对主梁局部受力影响较大。对于止推力较大的情况,采用锚固在横梁、底板和腹板角点处的连接拉杆止推方式较为合理可行。更多还原

【Abstract】 The article analyzes and compares three thrust modes of front-support form traveler for concrete cable-stayed bridge.The use of the different thrust types will greater affect the partial stress of the main girder.It is more reasonable and feasible to use the connecting pull-rod thrust mode anchored at the angle of crossbeam,bedplate and web if the thrust force is larger.更多还原
