实际施工中影响隧道锚索预应力损失的因素众多,相比于基坑和边坡用锚索,隧道中锚索预应力损失的影响因素更加复杂,并且各因素间互相关联.为探究不同因素对预应力损失影响的方式和程度,通过结合过往对锚索预应力损失的研究成果,将影响锚索预应力的因素划分为系统损失、短期损失和长期损失,并对隧道锚索预应力损失的影响因素和损失机理进行了总结和归纳,从而更加清晰地认识了各因素对预应力的影响方式,其对隧道锚索的设计、施工和管理有一定参考价值,有利于提高锚固工程的经济效益和社会效益.
ANALYSIS OF INFLUENCING FACTORS OF PRESTRESS LOSS OF TUNNEL ANCHOR CABLE
There are many factors affecting the prestress loss of tunnel anchor cables,and the influencing factors of anchor prestress loss in tunnels are more complex than those for foundation pits and slopes,and the factors are related to each other.In order to explore the way and degree of influence of different factors on prestress loss,the factors affecting anchor cable prestress are divided into system loss,short-term loss and long-term loss by combining the research results of previous researchers on anchor cable prestress loss,and the influencing factors and loss mechanism of tunnel anchor prestress loss are summarized and summarized,so as to have a clearer understanding of the influence of each factor on prestress,which has certain reference value for the design,construction and management of tunnel anchor cable,which is conducive to improving the economic and social benefits of anchoring engineering.
