| 摘 要： | 锚墩框格梁预应力锚索体系的分析涉及土、框格梁和锚墩的相互作用，故受力机理复杂，在将锚墩框格梁预应办锚索体系离散成横向长梁、纵向长梁和锚墩的基础上，提出了锚墩框格梁预应力锚索体系分析模型，与已有模型相比，该模型数学表达式考虑了土、锚墩与框格梁之间的相互作用，还根据框格梁受力特征，提出了锚墩的合理间距范围，实例分析中计算所得的内力分配与现场测量的结果吻合良好。

| Abstract: | The work mechanics of frame pier with prestressed cable is very complicated owing to the interaction between soil, frame and pier. By dismembering the system of frame pier with prestressed cable into orthogonal continuous beams and pier on elastic foundation, a simpler model incorporating the interaction between soil, frame and pier is presented. Design recommendation for frame spacing is suggested. A case study is carried out, indicating that the internal force distribution formula presented in this paper corresponds well to the measured data. |
