【摘要】：最近二三十年,鐵路系統(tǒng)和公路系統(tǒng)發(fā)展迅猛,橋梁越來(lái)越廣泛的應(yīng)用于跨越大江大河或者其他障礙物的工程中。深水基礎(chǔ)應(yīng)用于眾多橋梁工程中,深水基礎(chǔ)的特點(diǎn)有周期很長(zhǎng)、難度很大、風(fēng)險(xiǎn)很高等,這也成為橋梁施工的重要因素。因此,在進(jìn)行橋梁施工過(guò)程中,對(duì)深水基礎(chǔ)的研究變得非常有意義。以水陽(yáng)江大橋480#和481#橋墩基礎(chǔ)的施工為研究對(duì)象,系統(tǒng)研究了該橋水中承臺(tái)的施工技術(shù)和拉森IV型鋼板樁圍堰在該工程中的具體應(yīng)用。研究了鋼管樁平臺(tái)的設(shè)計(jì)和安裝施工、承臺(tái)的具體施工過(guò)程,以及大體積混凝土的溫控技術(shù)。論文對(duì)水陽(yáng)江大橋鋼板樁圍堰的吊裝施工、插打施工、土方開(kāi)挖、內(nèi)部支撐的安裝進(jìn)行了研究,又對(duì)鋼板樁圍堰系統(tǒng)在開(kāi)挖過(guò)程中的不同工況下進(jìn)行了驗(yàn)算。對(duì)大體積混凝土進(jìn)行了施工技術(shù)優(yōu)化,并通過(guò)溫度監(jiān)測(cè),對(duì)大體積混凝土的溫降效果進(jìn)行了驗(yàn)證,為以后類(lèi)似工程施工提供經(jīng)驗(yàn)。
[Abstract]:With the rapid development of railway system and highway system, bridges are more and more widely used in large rivers and other obstacles. Deep-water foundation is used in many bridge projects. The characteristics of deep-water foundation include long period, great difficulty and high risk, which has become an important factor in bridge construction. Therefore, in the process of bridge construction, the study of deep-water foundation becomes very meaningful. Taking the construction of 480# and 481# piers foundation of Shuiyang River Bridge as the research object, the construction technology of the cap in water and the concrete application of Larsen IV steel sheet pile cofferdam in the project are systematically studied. The design and installation of the steel pipe pile platform, the concrete construction process of the cap and the temperature control technology of the mass concrete are studied. In this paper, the hoisting construction, inserting construction, earthwork excavation and installation of internal support of steel plate pile cofferdam of Shuiyang River Bridge are studied, and the checking calculation of steel plate pile cofferdam system under different working conditions during excavation is also carried out. This paper optimizes the construction technology of mass concrete and verifies the effect of temperature drop of mass concrete through temperature monitoring, which provides experience for the construction of similar projects in the future.
