摘要:
为保证舍里甲大桥成桥后和施工过程中桥梁的线形以及受力状态符合设计要求，利用有限元软件Midas/Civil建立全桥模型，通过影响矩阵法等方法。对桥梁施工过程中的线形、应力和索力进行施工控制，并将施工过程中得到的实测值与有限元软件的计算值进行对比分析。结果表明:拱肋、主梁的线形和应力与设计值吻合良好，数值在合理范围内;吊杆索力大小分布均匀，索力实测值与计算值的误差在设计允许的范围内,达到了良好的控制效果，为今后同类桥梁施工提供有效参考。
Abstract:
As a through steel box tied arch bridge, the main bridge of Shelijia Bridge has a total length of 120m and is located in the Economic Development Zone of Nanchang. A bridge model was established by means of Midas/Civil, and the influence matrix method and other methods were used to control the linear shape, stress and cable force in the construction process of the bridge, which ensured the alignment and forced state of the bridge meet the design requirements after the bridge was formed. The field test data obtained during the construction process were compared with the calculated values of the finite element software, providing an effective reference for future bridge construction. The results showed that the alignment, stress o-f the arch rib and main girder in the bridge stage are consistent with the calculated values, which are within a reasonable range. The suspender cable forces are well distributed, and the error between the measured value and the calculated value is within the allowable range of the design. It is well controlled during the construction period and provides an effective reference for similar bridge construction in the future.
