摘要
以聊城某斜拉桥工程为依托,建立Midas/Civil空间有限元模型进行分析,就桥塔施工过程中的应力、塔顶偏位、基础沉降、温度进行研究.监控结果表明,大桥主桥结构状态良好,主塔偏位实测数据与理论数据吻合较好,应力测点均无拉应力出现且偏差值均在规范容许范围内.
Abstract
Based a cable-stayed bridge project in Liaocheng,Midas/Civil spatial finite element model is established for analysis,and the stress,tower top deviation,foundation settlement and temperature during bridge tower construction are studied.The monitoring results show that the main bridge structure of this large bridge is in good condition,the measured data of main tower deviation are in good agreement with the theoretical data,there is no tensile stress at the stress measuring points,and the deviation values are within the allowable range ofthe specification.
