| 摘 要： | 该文以某独塔自锚式悬索桥为例,描述了该桥施工控制中的张拉过程,研究了自锚式悬索桥施工中的力学特性。考虑结构承载能力和张拉设备能力等约束条件,通过张拉次数和接长杆数量的优化方法,进行了吊杆张拉方案比选。重点研究了缩短吊杆张拉施工工期和避免混凝土梁开裂问题,可为混凝土自锚式悬索桥施工控制提供借鉴。

| Abstract: | Taking a single-pylon serf-anchored suspension bridge as an example,the article describes the tensioning process in the construction control of this bridge,and studies the mechanical properties in the construction of the self-anchored suspension bridge.Considering the restricting conditions of structural bearing capacity and tensioning equipment capacity,and optimizing the tensioning times and the lengthening hanger number,the article compares ans selects the tensioning hanger schemes. The article focuses s... |
