| 摘 要： | 首先通过分析齿板锚固区的应力分布规律,揭示了引起齿板锚固区拉应力集中的5种典型局部作用效应.根据主应力迹线指示的力流传递路径以及局部区域的力流平衡关系,提出了齿板锚固区拉压杆模型的基本构形,在此基础上,进一步研究了定量化几何构形的确定方法和依据.以所提出的拉压杆模型为基础,结合AASHTO规范,给出了预应力齿板锚固区的...

| Abstract: | Through stress distribution analysis for an anchorage plate,five typical local action effects which lead to tensile stress concentration were revealed.Based on the load paths indicated by principal stress trajectories and the balance relationship among force flows,the basic configuration of strut-and-tie model for anchorage plate was proposed.In addition,further study on the approach and the basis for determining the quantitative geometric configuration was carried out.By the proposed method and as per rele... |
