| 摘 要： | 锚杆框架梁是一种较好的加固膨胀土路堑边坡方式，但其设计理论依据仍不统一，未形成成熟的规范，多依靠工程经验。Winkler地基梁和半无限弹性体理论被用来计算框架梁的内力，在Winkler假设的前提下，着重分析了现浇梁和预制梁在不同长度条件下的内力分布。结果表明：框架梁的设计完全依据膨胀力是欠合理的，建议采用Winkler地基梁和半无限弹性体理论计算框架梁的内力，并结合工程实例，提出了相关的建议。

| Abstract: | Anchor frame beam is a good method for strengthening the expansive soil roadcut slope. However its design theory is still not uniform and there is no any code to be followed. Engineering experiences are important for the design of anchor frame beam. The assumption of Winkler foundation beam and semi-infinite elastic theory are used for calculating the internal forces of anchor frame beams.The internal force distributions of different length beams are analyzed.The results show that it is illogical to design the frame beam just by expansive force. It is suggested that the internal forces of anchor frame beam to be calculated with Winkler foundation beam and semi-infinite elastic theory. At the same time the pertinent proposal for designing frame beam is offered based on an actual project. |
