结合某桥的实际情况,对自锚式悬索桥吊杆张拉进行了理论和施工分析。对吊杆分6轮进行张拉,6轮张拉吊杆的范围和力有很大区别。利用检测设备测得张拉过程中各吊杆的受力状态、鞍座位移、塔顶变形等,均较好地满足了施工要求,说明该自锚式悬索桥桥的吊杆张拉方法是可行的。针对该座桥吊杆的张拉方法提出了改进的方法,对其它自锚式悬索桥的吊杆张拉有一定的参考借鉴作用。
According to the actual situation of a bridge, the tension and tension of self-anchored suspension bridge are analyzed theoretically and constructionally. The boom is divided into 6 rounds of tension, 6 rounds of tension boom range and force are very different. Using the testing equipment to measure the force state of each boom, the displacement of the saddle and the deformation of the tower during the tensioning process, the requirements of the construction are well met, which shows that the method of tensioning the boom of the self-anchored suspension bridge is feasible. of. Aiming at the method of tensioning the suspension bridge of the bridge, an improved method is proposed, which can be used as a reference for the tensioning of the suspension rod of other self-anchored suspension bridges.
