| 摘 要： | 通过某悬索桥隧道锚锭进行的12.5:1的结构缩尺模型锚锭张拉试验,获得了张拉力及对应的隧道围岩变形试验数据,建立了围岩极限承载力灰色GM(1,1)预测模型,对所获得的37个预测值进行数据分析和处理,预测出岩体极限承载力超过6倍设计荷载,锚锭设计是安全的。

| Abstract: | Tensile force and the corresponding data of the tunnel wall rock deformation are obtained by a suspension bridge tunnel anchorage tensile model tests,whose reduced scale is 12.5:1. The grey forecast model(GM 1,1) of wall rock bearing capacity is established; and the thirty seven forecasting data obtained from the model are analyzed.The rock limit bearing capacity forecasted is six times of its design load,so the anchorage design is safe. |
