本文根据有关文献和工程调查资料,总结了我国水工混凝土结构领域研究和应用预应力锚固技术的状况,建议了钱索张拉控制应力和预应力损失的取值方法,提出了目前预应力锚固技术向规范化体系方向发展急需解决的问题。本文工作可供水工混凝土结构设计规范增订相应条文时参考.
Based on the relevant literature and engineering survey data, the paper summarizes the research and application of prestressed anchoring technology in the field of hydraulic concrete structures in our country, and proposes the method of determining the control stress and the prestress loss of the cable tensioning. The current prestressed anchoring Technology to standardize the direction of the development of the system urgently needed to solve the problem. The work of this paper can be used as a reference for the design of hydraulic concrete structures when updating the corresponding provisions.
