【摘要】：迄今为止,拱桥已经有了三千多年的发展历史了,是比较古老的桥型之一。相比起其悠长的发展历史,钢管混凝土结构的发展不过短短百年,但是钢管混凝土结构在工程上的应用却发展得很快。在拱桥领域中,钢管混凝土结构以其优越的跨越能力获得广大桥梁工程师的喜爱,尤其是需要在某些深沟、峡谷上建设桥梁时。虽然钢管混凝土拱肋在安装过程中,采用的是先架设好空钢管再拓送混凝土的办法,由于结构自重较轻,使架设施工时更加便捷,然这种桥梁的结构形式起步较晚,一些设计理论和设计规范还不够完善。从现今的发展状况看,钢管混凝土拱桥的跨径越来越大,对于施工控制的要求越来越高。本文论述的汉阳河特大桥属于上承式钢管混凝土拱桥,在施工过程中采用的是缆索吊装施工法,由于缆索吊装能力有限,所以拱肋必须分节段进行拼装。这就给施工控制提出了一个很深刻的问题,即如何控制拱轴线的线形,使其能够达到设计预期的状态。本文就汉阳河特大桥的施工控制成果,对这一问题进行研究和探讨。首先,简要阐述钢管混凝土拱桥的由来、特点及其发展历程,并对拱桥施工控制理论及方法做一下简要的介绍,阐明拱桥施工控制的内容、目的及意义。通过这些,让我们对拱桥的施工控制有一个浅要的了解,如施工控制的分析方法,如何对拱肋的线形进行计算分析等。其次,采用Midas/Civil有限元计算软件对汉阳河特大桥的施工过程进行模拟,得出在不同的情况下拱肋的变形情况,为施工过程中控制标高的设置提供参考。通过对汉阳河特大桥拱肋架设过程进行仿真计算分析和实时跟踪分析,确保成桥线形能够和设计线形符合。针对拱肋吊装过程中引起线形变化的因素进行分析,通过理论计算得出拱肋的预抬高值,起到优化施工的作用。
[Abstract]:So far, the arch bridge has been developed for more than three thousand years. It is one of the oldest bridge types. Compared with the long history of development, the development of the concrete filled steel tube structure is only a hundred years, but the application of the concrete filled steel tube structure has developed rapidly. In the field of arch bridge, the concrete filled steel tube structure is superior to the concrete. In the course of installation of concrete filled steel tube arch ribs, the method of setting up the empty steel pipe and reextending the concrete in the process of installing the concrete filled steel tube arch ribs is more convenient, but the structure form of the bridge is more convenient. In the late start, some design theories and design specifications are not perfect. From the current situation of development, the span of the concrete filled steel tube arch bridge is becoming more and more large and the requirements for the construction control are more and more high. The Hanyang River Bridge, which is discussed in this paper, belongs to the concrete filled steel tube arch bridge. In the construction process, the cable hoisting construction method is adopted. The cable hoisting capacity is limited, so the arch rib must be segmented. This gives a very deep problem to the construction control, that is, how to control the line of the arch axis so that it can reach the desired state of design. In this paper, the construction control results of the Hanyang River Bridge are studied and discussed. First, a brief explanation is given. The origin, characteristics and development course of the concrete arch bridge are introduced, and the construction control theory and method of the arch bridge are briefly introduced. The content, purpose and significance of the construction control of the arch bridge are clarified. Through these, we have a shallow understanding of the construction control of the arch bridge, such as the analysis method of the construction control, and how to shape the arch rib. Secondly, Midas/Civil finite element software is used to simulate the construction process of the Hanyang River Bridge, and the deformation of the arch rib in different conditions is obtained, which provides reference for the setting of the control elevation during the construction process. Through the simulation and analysis of the erection process of the arch rib of the Hanyang River bridge, the simulation analysis and the real-time follow are carried out. The trace analysis ensures that the linear shape of the bridge can conform to the design line shape. According to the analysis of the factors caused by the change of the line shape during the hoisting process of the arch rib, the pre elevation value of the arch rib is obtained by theoretical calculation, which plays an important role in the optimization of the construction.
