摘要
通过跨S329省道悬臂连续梁的张拉施工实例,论述了预应力筋张拉中的应力控制技术和理论伸长值的准确实用计算方法,并对理论伸长值与实测伸长值进行比较分析,判断桥梁预加应力的准确性和可靠性。
Through stretch construction example of cantilever continuous beam cut across S329 province road,the prestressed stretch stress control technology and theoretical elongation value correct operational calculation method were discussed,the theoretical elongation value and practical elongation value were analyzed comparison,the bridge prestress accuracy and reliability were identified.
