摘要
以兰武二线铁路某段深挖路堑高边坡预应力锚索加固为背景,通过对其中若干个锚索锚固力的试验及观测,主要探讨了预应力锚索锚固力系统和松弛与变形两个方面的损失,这对确定高边坡张拉荷载及锚索施工具有一定的指导意义。
Taking strengthening high slope in a certain deep-excavated cutting section in Lan-Wu secondary railway with pre-stressed anchor cable as background,the author discusses anchorage force system of pre-stressed anchor cable through several tests and observations anchor cable＇s anchorage force,which has certain instructive meanings to confirm tensioned load of high slope and anchor cable construction.
