关于提高粘土质边坡中预应力锚索锚固力的探讨

Discussion on improving the anchoring force of clay slope

当今工程对于稳定性差的粘土质边坡多采用锚索格构梁或锚索抗滑桩支护,但锚索锚固段达到设计强度往往需要锚入岩层中。则在土层深厚区域,锚索自由段过长,造成工程投资增加。本文以作者长期接触工程实际得到的经验出发,提出一种提高粘土层中锚索锚固力的设想及其计算模型,以供同行探讨。

In today＇s engineering for clay slope stability using anchor lattice beam or anchor anti slide piles, but the anchoring section reached the design strength often need to anchor into rock. In the deep soil layer, the cable free segment is too long, resulting in increased investment in the project. Based on the engineering practice and the experience of long-term contact, put forward a tentative plan to increase the clay layer in the anchoring force and its calculation model for peer discussion.
