连续梁0号块现浇支架反力法预压施工关键技术

The Key Construction Technology of Preloading Cast-in-siut Stents in No.0 Block of Continuous Beam with Reaction Method

对连续梁0号块现浇支架预压施工方法的选择进行对比分析,得出反力法具有方便快捷、安全可靠的优点,同时满足现场物资材料、人员设备和工期等要求。同时介绍了反力法施工过程中的前期准备、钢绞线受力计算、加载过程和卸载过程等技术要点。

Analyzing and contrasting the advantage of different methods to choosing the way to preloading the cast-in-siut stents of the No. 0 block of continuous beam,which showed that the reaction method is more easier and safer than others,meanwhile,it meet the requirements of materials,Personnel equipment and construction period. The construction process of reaction method including construction preparation,counting the force of steel strand,the loading order and the unloading order was introduced.
