摘要
介绍了丰都名山大桥主塔施工,采用在中塔柱设置主动横撑的方式消除主塔中塔柱塔肢外部不良应力状态,采用Midas Civil建立模型计算横撑应力状态,设计一种简易托架和横撑接头进行主动横撑预应力的施工。
The main tower construction of Fengdu famous mountain bridge is introduced. The external stress state outside the tower column of the main tower is eliminated by setting up active transverse bracing in the middle tower column. The stress state of the transverse bracing is calculated by Midas Civil model,and a simple bracket and transverse bracing joint are designed to carry out the pre stress construction of the active cross bracing.
