摘要
介绍预应力梁式桥悬臂施工控制的内容、方法,对预应力混凝土梁式桥的内力监测元件布置及应力监测数据误差的产生原因和影响因素进行了分析,对温度、预应力的监测以及施工预拱度的控制、线形控制进行了细致、深入的探讨与总结,以供广大工程技术人员参考。
By analyzing the internal force monitoring component layout and the causes and influencing fac- tors producing stress monitoring data errors, the paper introduces detailed methods for momintoring and control of prestressed beam bridge cantilever construction. The author further gives detailed and in-depth discussion and summarization on temperature control, prestress monitoring, construction of pre-camber control and linear control. This article provides a good reference for engineers and technicians.
