大吨位小半径环向预应力在斜拉桥索塔锚固区中的应用研究
The Research of Application of the Looped Prestressed Tendons with Large Tonnage and Small Radius in the Anchorage Zone of Cable-stayed Bridge Tower
【摘要】 目前我国大跨径斜拉桥索塔锚固区开始采用大吨位小半径环向预应力体系 ,该体系突破了现行《公路桥涵设计规范》的规定。结合武汉军山长江公路大桥索塔锚固区足尺模型试验及张拉工艺模型试验对该预应力体系在斜拉桥索塔锚固区中的应用作了深入的探讨
【Abstract】 Nowadays the large tonnage and small radius annular prestress system are applied in the anchorage region of large span cable stayed bridge construction in our country. The application of this system has been a breakthrough of the Design Specification of Highway Bridge and Culvert. In this article, the application of this system applied in the anchorage region of cable stayed bridge tower has been probed in close connection with the full scale model test of the anchorage zone of the Wuhan Junshan Changjiang River Bridge.
