摘要

岩土锚固工程结构随着时间的推移，锚固结构各组成部分的工作性能将由于各种原因而发生相应的变化，这些变化对锚索结构的长期工作性能产生重要的影响。研究锚索长期承载力性能检测与荷载补偿技术，首先要解决已锁定的锚索重新连接问题，再通过张拉检测锚索预应力和锚索承载力的变化。并补偿预应力损失，使之达到设计要求或最大可用值，以充分发挥预应力锚索的锚固作用。实践证明，该技术方法简单实用，易于技术人员掌握，是锚固工程施工、运营以及工后维护过程中，锚固结构长期工作性能检测与荷载补偿的有效方法之一，值得推广与应用

Abstract

In course of time

due to various reasons

the performance of each component of anchor cable will change. These changes will have an important impact on the long-term performance of anchor structure. The study of anchor cable long-term performance testing and load compensation

firstly

it is to solve the problem re-connecting of the locked anchor cable; secondly

to detect the prestress and the changes of bearing capacity of prestressed anchor cable by tension. To compensate the loss of prestress so as to achieve the design requirements or maximum value can be used to give full play to the role of prestressed anchor cable. It is proved that the technology is simple and practical and easy to master. It is one of effective methods of compensation for anchorage working condition long-term performance testing and load compensation. It is worthy of promotion and application
