Incremental-pushing-free construction method for cable saddle of cable-stayed and suspension cable cooperative system bridge
The invention discloses a cable saddle pushing-free construction method for a cable-stayed and suspension cable cooperative system bridge, which sequentially comprises the following steps of: building a shell of a bridge main tower, and installing a main cable saddle; part of the main beam sections are installed, and the main beam sections are temporarily and fixedly connected; according to the method, side span stay cables of a cable-stayed bridge section of a bridge are tensioned, a main tower is made to deviate towards the side span side, the number of the tensioned stay cables needs to be guaranteed, when a suspension bridge main cable is erected on an existing tower beam structure, the unstressed length of a side middle span cable section of the suspension bridge main cable is kept consistent with a design target, and meanwhile the suspension bridge main cable does not slide in a saddle groove of a main cable saddle; mounting a main cable of the suspension bridge; the anti-sliding safety coefficient of a main cable of the suspension bridge is obtained through calculation, and a main beam of the cable-stayed bridge part and a main beam of the midspan suspension bridge part are installed according to the obtained anti-sliding safety coefficient; pouring the composite section of the main tower; and completing the installation of the remaining cable-stayed bridge partial beam sections, the stay cables and the suspension bridge partial beam sections, relieving the temporary constraint of the main beam, and finally forming the bridge.
本发明公开一种斜拉悬索协作体系桥的索鞍无顶推施工方法，按照以下步骤依次进行：建造桥梁主塔的外壳，并安装主索鞍；安装部分主梁节段，将主梁节段临时固结；进行桥梁斜拉桥段边跨斜拉索的张拉，使主塔朝边跨侧偏移，张拉的斜拉索的数量需保证，在既有塔梁结构上架设悬索桥主缆时，悬索桥主缆的边中跨缆段无应力长度与设计目标保持一致，同时悬索桥主缆在主索鞍的鞍槽内不发生滑移；安装悬索桥主缆；通过计算得到悬索桥主缆的抗滑安全系数，并根据得到的抗滑安全系数进行斜拉桥部分的主梁和中跨悬索桥部分的主梁的安装；浇筑主塔的复合截面；完成剩余斜拉桥部分梁段、斜拉索与悬索桥部分梁段的安装，解除主梁的临时约束，最终成桥。
