岩体工程预应力锚索定位止浆环研制与应用

A Dcvelopment Study on the Localized Cement-proof Rjng Applied to Prestressed Anchor Rope

本文介绍了定位止浆环的工作机理、止浆材料的选择、室内试验结果，以及在隔河岩厂房边坡加固中的应用。试验结果与现场应用表明：定位止浆环是形成岩体工程预应力锚索内锚段的一种安全可靠、经济实用的较理想的构件，在岩体工程边坡加固处理工程中具有广泛的使用价值。

Introduced in this paper are the work mechanism of localized cement-proof ring,the selec-tion of cement-proof material,the results of laboratory experiment,and the application of this ring atthe site of project Geheyan. The experimental results and the onsite application show that the localized cement- proof ring is an ideal apparatus for the formation of inside anchorage length of prestressed an-chor rope.Being safe,reliable and economical,it can be extensively applied to the rock mass slope en-hancement.
