预应力锚拉桥台施工技术

Construction Technique of Prestressed Anchor Rod Land-pier

在太原小店汾河大桥施工过程中．实测了土对锚拉杆的摩阻力随时间的变化；实测了锚拉杆、梁、柱钢筋应力及锚拉杆、梁、柱位移变化情况，得到了一些重要结论，对工程设计与施工具有很大的参考价值。

In the construction of Xiao dian Fenhe bridge,the regularities of anchor rod fric-tion changing with time and rod lcngth,and strcsses and displacements of the anchor rod, beamand pile are measured in situ. Some important conclusions are obtained,which are good referencesto design and construction of rcal projects.
