岩质边坡中预应力锚索抗拔试验研究

The study of pullout testing of prestressed cables in a rock slope

在某高危边坡治理工程开始时,通过对16 m长600 kN的预应力锚索的抗拔试验,对预应力锚索抗拔试验过程进行了详细的分析,并验证和调整了相关设计参数,调整后的设计采用了18 m长的预应力锚索。

Through the pullout testing of 16 m long and 600 kN prestressed cables at the beginning of a high and dangerous slope stabilization works, detailed analyses are carried out to the pullout testing process of prestressed cables and the relevant design parameters are also verified and adjusted. After the adjustification, 18 m long prestressed cables are adopted in the design.
