摘要
介绍了魏家洲特大桥宜昌岸滑坡体的特点和锚索的设计，对锚索施工工艺、施工过程中质量控制要点进行了详细论述，并介绍了锚索现场试验的方法。结果表明对于弱～微风化岩层，采用压力分散型预应力锚索，可以避免锚固段受力岩层应力集中，增强锚固效果和减缓锚索应力损失时间，降低了不可靠因素，从而达到长期稳固边坡的目的。
It briefly introduced the landslide characteristic of the Yichang Bank coast of Weijiazhou Bridge and the design of anchorage cable. It detailed discussed the construction technology of anchorage cable and quality control in construction process. It introduced a method for field acceptance of anchorage cable. The results indicated that for weak weathered rock formation pressure dispersion - type prestressed anchorage cable could be applied to avoid stress concentration in the anchorage zone rock, to enhance the anchorage effect and to decrease the time of stress loss of the cables, which could decrease the unreliable factors and reach the object of long-term safe of slide slope.
