| 摘 要： | 现关于预应力锚索的研究多集中在荷载传递与加固机理方面,而对于运行期内锚段载荷分布随时间变化及其与锚索有效预应力的关系研究则较少.基于某水电站预应力锚索现场试验,研究了锚索张拉过程中的内锚头变位与内锚段载荷的非线性传递,及运行初期内锚段载荷分布随时间的调整变化规律及其与预应力变化间的影响.研究发现,拉力集中型锚索张拉后内...

| Abstract: | Though load distribution and anchoring mechanism of prestressed cable have been studied by lots of tests and theoretical analysis,the load distribution variation over time of inner-anchor segment and its relationship with anchor effective prestress are seldom studied.Based on in-site test of prestressed cable in a hydraulic power station,the authors analyzes the displacement of inner-anchor head and the nonlinear load transfer of inner-anchor segment during anchor pulling,and the variation of load distribut... |
