摘要
本文以大伙房水库输水(二期)工程中抚顺段为例,分析隧洞喷锚支护和预应力环锚混凝土衬砌工程锚具槽设置位置的不同对衬砌内部应力的影响,综合考虑设计施工各方面因素,设置相对合理的锚具槽夹角,以控制衬砌内部应力,减少应力变形。
In the paper,Fushun segment in Dahuofang Reservoir water diversion（ stage Ⅱ） project is adopted as an example. Influence of different setups of tunnel spray anchor bracing and pre-stressed ring anchor concrete lining engineering anchorage slot positions on lining internal stress is analyzed. Factors in all aspects of design and construction are comprehensively considered. Relatively rational anchorage slot inclined angle is set. Lining internal stress is controlled,and stress deformation is reduced.
