摘要

在边坡防护及滑坡治理工程中单孔复合型锚索获得了越来越广泛的应用。基于滑坡工程实例中的锚索抗拔试验，设计了一种既可获得锚索抗拔力和预应力损失，又可实现对单孔复合型锚索单元锚固段进行受力测试的装置，其原理是通过直接测定锚索中的单束钢绞线受力而获得锚索受力，详细地介绍了该装置的设计实现。利用这种新型的测试方法于某滑坡锚固工程验明了可行性，测试结果为相应地质条件下的锚索设计方案和锚索施工提供了直接依据，亦具有工程应用和参考价值

Abstract

The single borehole multiple anchor cables have been widely used in the fields such as slope protection and landslide remedial projects in these years. Based on the in-situ pull-out test of anchor cables in a landslide

this paper pays attention to how to test both the stress of anchorage segments and the loss of prestressing force. Accordingly

a new method is put forward and introduced in detail; the basic principle of the method is mainly accomplished by testing the stress of individual steel strands of anchor cables

whose feasibility is demonstrated in the engineering practice. Finally

the forces of individual steel strands which are located in different position along the borehole are successfully tested; the results provide direct proofs for the anchor cables design and construction in the condition of in-situ engineering geology

and have practical engineering applicative values.
