摘要
分析了岩石高边坡工程中预应力锚索地梁在张拉阶段和工作阶段的受力特点,指出二者的根本差异在于地基反力的变化。阐明预应力锚索地梁的内力计算应该分张拉阶段和工作阶段分别进行。介绍了用弹性半无限地基梁和连续梁的方法计算预应力锚索地梁的内力,并以工程实例说明了主要计算过程。
The model of forces of prestressed-cable beam-on-foundation during tension and consecutive working stages is analyzed. The principal force difference between the two stages is pointed out,which results from the variation of foundation reaction. The internal force of prestressed-cable beam-on-foundation should be respectively calculated for each stage. The model of beam on half-space elastic foundation can be used on the first stage and the model of continuous beam can be directly used on the next stage. The main calculation procedure is given by a practical project.
