摘要
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.
In this paper, the status of research on the technique of prestressed anchorage and its opplication in bydropower construction is summarized, and the methods for calculating tensile control stress and prestress loss are suggested. On the basis of these analysis, some questiones are presented for spacificating the technigue of prestressed anchorage.
