公路高边坡预应力锚索加固监测与分析

Monitoring and Analysis of Reinforcing High Side Slope of Highway with Prestressed Anchor

研究目的:对公路高边坡进行预应力锚固加固工程属隐蔽工程,关系到公路交通的安全。影响锚固效果的因素很多,对预应力锚固工程开展原位监测非常重要。研究结果:本文对锚索测力计的工作原理作了说明。对预应力锚索测力计在张拉过程中及锁定后锚固预应力的变化特征、损失作了分析,并以此说明锚索测力计在锚索施工及边坡监测中的作用。

Research purposes： To reinforce high side slope of highway with prestressed anchor belongs to concealed work that relates to the safety of highway. There are lots of factors influencing the anchoring effects, so it is very important to monitor the reinforcement with prestressed anchor in place. Research results：In this paper, the explanation is given to the working principle of anchor wire dynamic meter and the analyses of the change characteristics and loose of anchoring prestress in the cause of prestressed anchor wire dynamic meter being tensioned and after it being locked so as to show the effects of anchor wire dynamic meter in anchor wire engineering and monitoring reinforcement of side slope.
