| 摘 要： | 体外预应力索是体外预应力混凝土结构的主要受力构件,其耐久性决定着结构的耐久性。应当采取有效措施对体外预应力索进行保护。为防止预应力索发生腐蚀,可以采取预应力索镀锌、涂层、增加套管等方法。为了提高预应力索系统的耐久性,可以采取提高钢索的耐腐蚀性、使用新型体外索材料、改进锚具、保证体外索防腐体系的质量等多种措施。

| Abstract: | External pre-stressed cable is the main component of external pre-stressed concrete structure. The durability of the structure depends on component durability. It is necessary to take measures to protect external pre-stressed cable. In order to prevent the cable from corrosion, the methods of zinc plating, painting and casing pipe will be used. For enhancing durability of external pre-stressed cable system, such measures as using new material cable, enhancing cable anti-corrosion ability, improving anchor and ensuring cable system quality are taken. |
