摘要
压力分散型无粘结预应力锚索与常规的拉力型锚固体系相比,改善了内锚固段区域的受力状态。大量的应用成果表明,在同等地层条件下,其可以达到提高锚固力50%的效果。结合锦屏二级水电站进水口边坡采用压力分散型无粘结预应力锚索的工程实践,介绍了压力分散型锚索施工与质量控制的情况。
Comparing pressure dispersed bondless prestressed anchors with conventional tension anchorage system,stress conditions are improved in internal anchorage length area.A large number of achievements show that under same geological formation,anchor force can be increased by 50%.According to engineering practices in use of pressure dispersed bondless prestressed anchors in slope support for intake structure at Jinping Ⅱ hydropower station,construction quality control for this type of anchors are described.
