斜拉桥的施工是一项极其复杂的力学体系转换过程 ,必须进行施工监控。目前的施工监控是采用平面杆系的有限元法。针对仙桃汉江大桥 ,利用块体等空间单元 ,按照施工的真实步骤 ,逼真地建立了该斜拉桥一系列的空间计算模型。使得设计和监控更加逼近真实状态 ,对斜拉桥的建设起到了有益的推进作用
Cable-stayed bridge construction is an extremely complex mechanical system conversion process, construction monitoring must be carried out. The current construction monitoring is the use of planar finite element method. Aiming at the Han River Bridge in Xiantao, a series of spatial calculation models of the cable-stayed bridge are established in a realistic way by using space units such as blocks and so on. Making the design and monitoring closer to the true state, the construction of cable-stayed bridge has played a useful role in promoting
