摘　　要：永久性支护桩锚体系中对于永久性锚杆的长期有效性有较高的要求,是确保桩锚体系安全运行的重点,为此需要从设计、施工、试验、监测维护等阶段严格把关,对锚固段、自由段、封头等多维度进行控制。研究表明,对于永久性拉力型锚杆,从以上各阶段、各要素加以控制,能有效保证质量和安全。The long-term effectiveness of permanent support pile-anchor system has high requirements,which is the key point to ensure the safe operation of pile-anchor system,this requires strict control from the design,construction,testing,monitoring and maintenance stages,and multi-dimensional control of anchoring section,free section and head.The results show that the quality and safety can be effectively guaranteed by controlling the permanent tension anchor rod from the above stages and elements.
