摘要
针对某预应力锚索路基挡土墙,以静载条件下挡墙面板位移量和路基沉降量作为评价指标,确定适宜的锚索设计因素及水平,采用正交试验设计法优化锚固参数的组合方案,用FLAC^(3D)建立数值模型和分析计算,确定预应力锚索的最优设计参数,并结合现场监测证实了分析方法的可靠性。研究成果对预应力锚索挡墙工程设计具有重要的参考价值。
In this paper,an orthogonal experimental design method is adopted to optimize the anchorage parameters of a subgrade retaining wall with prestressed anchor cable. The displacement of the retaining wall and the settlement of subgrade under static load are selected as evaluation indexes,FLAC^（3D） is adopted to analyze the optimum parameters,and the reliability of the method is verified by field monitoring. The research results has practical significant in project construction.
