摘　　要：为了研究竖锚支护结构对基坑变形的影响,选取不同的竖锚入射角及对应的预加力,采用MidasGTS进行数值模拟,将不同竖锚入射角及对应的预加力与基坑变形的大小换算为等效水平刚度系数,揭示竖锚入射角、预加力与基坑变形之间的相互关系。In order to study the influence of vertical anchor supporting structure on foundation pit deformation,midasgts was used for numerical simulation analysis by selecting different incidence angles of vertical anchors and cor-responding different prestressing forces.By analyzing the relationship between the incident Angle of different vertical anchors and the corresponding prestressing force and the deformation of foundation pit,the relation-ship between the incident angle of vertical anchors,the prestressing force and the deformation of foundation pit is converted to the equivalent horizontal stiffness coefficient,so as to reveal the relationship between the in-cident Angle of vertical anchors,the prestressing force and the deformation of foundation pit.
