摘要
通过对上海市沪闵路高架道路二期工程中预制节段逐跨拼装施工的实践和总结,在介绍预制节段逐跨拼装施工的基础上,叙述了运用荷载转换这一关键工艺进行计算机辅助控制的原理与方法。计算机辅助控制的应用,不仅解决了复杂体系受力计算困难的问题,还提高了施工的安全性,保证施工质量,加快施工进度,效果良好。
Based on the practice and summary of Hu-Min Viaduct (II) construction in Shanghai by erecting prefabricated segments span by span, des-cription is made of the mechanism and way of computer-aided control (CAC) over the load transformation, a key step of workmanship. The application of CAC overcame the difficulty in the complicated calculation of forces on the system, and also got satisfactory results such as higher operation safety, better construction quality, and shorter construction period.
