摘要
根据三峡临时船闸及升船机高边坡系统锚杆应力状态的监测成果 ,结合测点地质条件 ,详细分析了锚杆应力的边坡开挖效应、温度效应和时效变形效应。
Based on the monitoring results of stress state of systematical bolts at temporary shiplock and boat lift slope of the Three Gorges Project,and combined with the geological condition around every bolt,the effect of excavation and temperature and timedependent deformation on bolt stresses is described.The control over temperature and timedependent deformation of rock mass by bolts is discussed,and the weakening of the bolting effects caused by the cyclics deformation in rock mass is also demonstrated in this paper.
