摘　　要：预应力混凝土结构因其自重轻、跨越能力强等优势,被广泛应用于西藏地区的公路桥梁建设。预应力技术是预应力混凝土结构的生命线,其施工质量必然是质量控制的重点内容之一。通过系统梳理在监督检查工作中发现的问题,并调研分析广东省锚下有效预应力检测应用效果,结合西藏地区在公路桥梁预应力施工质量控制的需要,对西藏地区开展该项检测的必要性及其不足之处进行了讨论、思考。Prestressed concrete structures have been widely used in highway and bridge construction in Tibet due to their advantages of light weight and strong spanning ability.Prestressing technology is the lifeline of prestressed concrete structures,and its construction quality must be one of the key contents of quality control.Being based on the need for quality control of highway bridge prestressing construction in Tibet,the necessity and deficiencies for this test in Tibet have been discussed.

关 键 词：锚下有效预应力检测 预应力施工 质量控制
