预应力锚索在青海黑泉水库调压井除险加固中的应用

为了阐明预应力锚索技术的施工工艺及其高寒地区的应用效果,结合青海黑泉水库调压井高边坡除险加固工程实例,对预应力锚索技术的施工工艺进行论述,并对施工中如何最大限度的发挥岩体能量、确保边坡稳定,提出了措施和技术方案。应力测试结果证明,只要施工工艺恰当,预应力锚索在高寒地区边坡病害治理中同样可以发挥良好的加固效果。

The application of the prestressed anchor cable in the surge shaft of Heiquan Reservoir reinforcement of Qinghai

In order to clarify the prestressed anchor cable technology,construction technology and its application results in cold regions,taking the surge shaft of Heiquan Reservoir in Qinghai as an example,this paper expounds the prestressed anchor cable technology,construction technology,and how to maximally exert the rock energy during the construction,to ensure slope stability,and proposed the measures and technical solutions.The stress test results proved that,as long as the proper construction process,the prest...
