摘　　要：成品索式锚固体系已在悬索桥锚碇工程中得到越来越多的应用。针对有弯曲预应力线段的锚碇工程,分析弯曲线段对锚固体系的影响,创新设计和试验研究一种含分丝管结构的多股成品索式锚碇锚固体系。经试验与工程应用表明,该新型锚固体系解决了预应力锚索在隧道锚体中弯曲锚固和更换难题,适用于有弯曲预应力线段的锚碇工程。The finished cable anchoring system has been used more and more in the anchorage engineering of suspension bridge.Aiming at the anchorage projects of curved pre-stressed line section,the influence of curved line section on the anchoring system is analyzed.A multi-strand finished cable anchorage anchoring system consisting of sleeve structure is innovatively designed and experimentally studied.The experiment and engineering application show that this new type of anchoring system can solve the curved anchorage and replacement problems of the pre-stressed anchor cable in the tunnel anchor body,and is suitable for the anchorage engineering of curved pre-stressed line section.
