5) low retracting twice pre-stressed anchorage
低回缩二次张拉预应力钢绞线锚具
1.
Study has been made to measure pre-stress lose of tendons in web which low retracting twice pre-stressed anchorage has been used, through experimental model bridge and actual bridge.
而低回缩二次张拉预应力钢绞线锚具以其预应力损失小的特点,应用于箱梁腹板能有效提高永存竖向预压应力值,在对箱梁腹板斜裂缝的防治上有独特的优势,本文以二次张拉预应力钢绞线为研究对象,进行了以下几个方面的研究:1、通过试验室模型和实桥对低回缩二次张拉预应力锚具应用于腹板竖向预应力的预应力损失进行了测试,重点测试了其由于接缝压缩、锚具变形及回缩引起的预应力损失值、弹性压缩值、松弛损失值、收缩徐变损失值,并对影响预应力损失的因素进行了分析。
