摘要
后张法施工时钢绞线伸长值变化的关键因素是预应力筋的弹性模量和孔道摩擦系数。本文结合二个连续梁桥施工实际,探讨伸长值偏差原因及校核标准。
Under construction elastic modulus of prestressting tendon and loss due to duct friction are the key factor that cause steel strand extension change by posttensioning method.
The article, according to construction experince of two continuous beam bridge, try to find out the cause of strand extension change and standard of calibration.
