The test included anchoring force of prestressed anchor cable, frictional coefficients, stress of concrete and steel bar and structure deformation.
测试内容包括预应力锚索锚固力、摩阻系数、混凝土和钢筋应力以及结构变形。

Finally, the influence of frictional resistance factors on the controlled tensioned stress is discussed and the general principle and requirements of field measurement are presented.
最后讨论了摩阻系数对张拉控制应力的影响，提出现场测试的一般性原则和要求。
