| 摘 要： | 预应力锚杆式挡土墙是一种新型有效的基坑支护结构,需要一种合理的工程计算方法.挡土墙锚杆试验表明,锚杆的预应力随着深度变化而不同,在稳定分析和位移计算时,要考虑相应的折减系数.在试验的基础上,根据地基反力系数M法,建立了弹性挡土墙的有限元模型,通过求解,提出了预应力锚杆式挡土墙变形的工程计算方法,并结合工程实例,对该方法进行了验证,验证结果与试验数据吻合较好,为预应力锚杆式挡土墙结构设计提供了科学的估算依据,对工程实践具有重要的参考价值.

| Abstract: | A new engineering method for calculating the retaining wall with prestressed anchored bar is needed.The prestress of vertical anchored bar changed as the deepth changed and the discount coefficient was considered on some experimental results.According to M-method,the FEM model of a elastic retaining wall were established on the base of experiment.So in the end,A new engineering method is presented by a power series solution.Comparisons are made of the the solution results with those of the test which shows ... |
