【摘要】：迄今為止,拱橋已經(jīng)有了三千多年的發(fā)展歷史了,是比較古老的橋型之一。相比起其悠長(zhǎng)的發(fā)展歷史,鋼管混凝土結(jié)構(gòu)的發(fā)展不過(guò)短短百年,但是鋼管混凝土結(jié)構(gòu)在工程上的應(yīng)用卻發(fā)展得很快。在拱橋領(lǐng)域中,鋼管混凝土結(jié)構(gòu)以其優(yōu)越的跨越能力獲得廣大橋梁工程師的喜愛(ài),尤其是需要在某些深溝、峽谷上建設(shè)橋梁時(shí)。雖然鋼管混凝土拱肋在安裝過(guò)程中,采用的是先架設(shè)好空鋼管再拓送混凝土的辦法,由于結(jié)構(gòu)自重較輕,使架設(shè)施工時(shí)更加便捷,然這種橋梁的結(jié)構(gòu)形式起步較晚,一些設(shè)計(jì)理論和設(shè)計(jì)規(guī)范還不夠完善。從現(xiàn)今的發(fā)展?fàn)顩r看,鋼管混凝土拱橋的跨徑越來(lái)越大,對(duì)于施工控制的要求越來(lái)越高。本文論述的漢陽(yáng)河特大橋?qū)儆谏铣惺戒摴芑炷凉皹?在施工過(guò)程中采用的是纜索吊裝施工法,由于纜索吊裝能力有限,所以拱肋必須分節(jié)段進(jìn)行拼裝。這就給施工控制提出了一個(gè)很深刻的問(wèn)題,即如何控制拱軸線的線形,使其能夠達(dá)到設(shè)計(jì)預(yù)期的狀態(tài)。本文就漢陽(yáng)河特大橋的施工控制成果,對(duì)這一問(wèn)題進(jìn)行研究和探討。首先,簡(jiǎn)要闡述鋼管混凝土拱橋的由來(lái)、特點(diǎn)及其發(fā)展歷程,并對(duì)拱橋施工控制理論及方法做一下簡(jiǎn)要的介紹,闡明拱橋施工控制的內(nèi)容、目的及意義。通過(guò)這些,讓我們對(duì)拱橋的施工控制有一個(gè)淺要的了解,如施工控制的分析方法,如何對(duì)拱肋的線形進(jìn)行計(jì)算分析等。其次,采用Midas/Civil有限元計(jì)算軟件對(duì)漢陽(yáng)河特大橋的施工過(guò)程進(jìn)行模擬,得出在不同的情況下拱肋的變形情況,為施工過(guò)程中控制標(biāo)高的設(shè)置提供參考。通過(guò)對(duì)漢陽(yáng)河特大橋拱肋架設(shè)過(guò)程進(jìn)行仿真計(jì)算分析和實(shí)時(shí)跟蹤分析,確保成橋線形能夠和設(shè)計(jì)線形符合。針對(duì)拱肋吊裝過(guò)程中引起線形變化的因素進(jìn)行分析,通過(guò)理論計(jì)算得出拱肋的預(yù)抬高值,起到優(yōu)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.
