文摘:对北京东方广场基坑支护中锚杆预应力的监测及其所出现的问题进行了分析，说明张拉过程中所存在的问题(预应力损失、偏心荷载等) 。 - Combined with the full scale models tested in - situ of prestressed concrete penstock with double circle unbonded strands and single circle bonded strands of xiaolangdi multipurpose dam project of yellow river , the advantages and disadvantages of two different prestressed systems are analyzed , the concrete stress distributions of the prestressed concrete penstock are induced and summarized during the whole tensioning strands stage . the consistence among the test results , the theory calculating and the three dimensional finite element analysis is proved . therefore , the theoretical method of prestressed concrete penstock is feasible
结合黄河小浪底水利枢纽工程在施工现场进行的采用双层双圈环形无粘结预应力钢绞线和单圈有粘结预应力钢绞线对排沙洞衬砌混凝土施加预应力的1 ： 1模型试验，对比分析了两种后张预应力施工体系的优劣，归纳总结了预应力筋束张拉过程中预应力混凝土压力管道结构管壁混凝土的内力分布规律，验证了模型试验实测数据、理论计算和三维有限元分析结果的一致性，确定了预应力混凝土压力管道理论计算方法的可行性。 - Been conducted accurately on prestress losses due to friction and due to the deformation of ahchorage devices and on interrelation between the different prestressing tendon during the course of tension . digital and sensing technology was first utilized to carry out the investigation on the influence of fluctuations of temperature on prestress . it is concluded that prestressing construction of reinforced concrete frame structure of high building without taking the effect of temperature into account simply could n ' t satisfy the requirement of quality criteria in force
本文对预应力摩擦损失、锚固损失以及不同的预应力筋在张拉过程中的相互影响进行了精确的现场试验研究，首次利用数字传感技术完成了温度变化对预应力影响的研究；得出了在高层钢筋混凝土框架结构施工中，不考虑温度影响的预应力施工，根本满足不了现行质量标准要求的重要结论。
