The authors described the structure of a newly - developed wedge-tube bolt, its reinforcement principles and anchoring performance, and the results of in situ pull test and productive applications.
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。
