关于预应力锚索抗滑桩内力计算方法的讨论

Prestressed archoring cable with anti-sliding pile calculation of internal forces of discussion Discussion of Internal Force Calculation of Prestressed archoring cable with anti-sliding pile

采用横向变形约束弹性地基梁法设计预应力锚索抗滑桩,按照变形协调原理计算锚索拉力、抗滑桩的位移和桩身内力,并将这种方法用于某一深挖路堑高边坡的预应力锚索抗滑桩工程,根据现场实测结果,讨论了该内力计算方法的合理性。

In the construction process of a highway deep road cut slope, it was reinforced by means of anti - sliding piles and pre- stressed anchorages, in the course of construction and operation, long term monitoring of anti - sliding piles and prestressed anchorages was carried out. The monitoring information was analyzed and fed back in time. the influence factors of landslide deformation were researched and the deformation tread was predicted. It has been proved that the observed data can correctly reflect the deformation of the landslide and meet the requirement of timely treatment.
