| 摘 要： | 自承载式预应力锚索是一种不需要注浆即可进行张拉锁定的拉压复合型预应力锚索，适合于滑坡灾害应急抢险的快速锚固工程施工。本文结合现场试验数据，分析了自承载式预应力锚索的张拉力、锚索应力分布规律，并与普通拉力集中型锚索进行对比，阐明自承载式预应力锚索不仅有不注浆即可张拉发挥快速锚固作用的特点，同时自承载式预应力锚索锚固段的应力分布均匀，能充分发挥锚固段全长的锚固作用。

| Abstract: | Self-bearing pre-stressed anchor cable is a kind of tension and pressure compound pre-stressed anchor cable, which can be locked by tensioning without grouting, and is suitable for the rapid anchoring engineering construction of the landslide disaster emergency rescue. Combined with field test data, this paper analyzes the integral tension and anchor cable stress distribution laws of the self-bearing pre-stressed anchor cable and compares this cable with common tensile anchor cable, it is shown that the self-bearing pre-stressed anchor cable not only has the characteristics of rapid anchoring without grouting, but also has uniform stress distribution in anchorage section to fully play the anchoring function in the whole anchoring section, which reflects the advantages of this new type of pre-stressed anchor cable. |
