【摘要】：橋梁建設(shè)環(huán)境復(fù)雜、施工條件差、不安全因素動(dòng)態(tài)變化快、安全誘因復(fù)雜和主體從業(yè)人員流動(dòng)性大等原因，多年來(lái)橋梁工程施工過(guò)程中安全事故呈現(xiàn)“易發(fā)、頻發(fā)、多發(fā)”等特點(diǎn)，且事故后果嚴(yán)重。確保橋梁建設(shè)安全尤為重要。安全生產(chǎn)，，重在預(yù)防。針對(duì)采用懸臂施工的預(yù)應(yīng)力混凝土連續(xù)梁橋，本文以高月塘大橋?yàn)榛A(chǔ)，研究其施工安全控制及施工安全風(fēng)險(xiǎn)評(píng)估，其主要的研究工作及成果如下： （1）運(yùn)用Midas/Civil2010軟件對(duì)高月塘大橋建立有限元模型，進(jìn)行PSC驗(yàn)算，驗(yàn)證橋梁結(jié)構(gòu)設(shè)計(jì)的安全。 （2）研究高月塘大橋設(shè)計(jì)標(biāo)高、成橋預(yù)拱度、施工預(yù)拱度、掛籃變形，得出高月塘大橋前期立模標(biāo)高與控制方法。 （3）對(duì)高月塘大橋進(jìn)行施工安全風(fēng)險(xiǎn)評(píng)估研究，并提出相應(yīng)的安全措施。 本文以高月塘大橋?yàn)橐劳�，從結(jié)構(gòu)安全、施工安全控制、施工安全風(fēng)險(xiǎn)評(píng)估三個(gè)方面進(jìn)行了研究，對(duì)高月塘大橋安全施工與管理有實(shí)際的指導(dǎo)意義，同時(shí)可為采用懸臂澆筑法施工的預(yù)應(yīng)力混凝土連續(xù)梁橋等類(lèi)似工程的安全施工與管理提供參考。
[Abstract]:The bridge construction environment is complex, the construction condition is poor, the unsafe factor changes rapidly, the safety inducement is complex and the main body employee mobility is big, the safety accident in the bridge engineering construction process presents the "easy to happen, frequent occurrence" for many years, Multiple "and other characteristics, and serious consequences of the accident." It is particularly important to ensure the safety of bridge construction. Safety in production, emphasis on prevention. Based on the Gaoyuetang Bridge, the construction safety control and construction safety risk assessment of the prestressed concrete continuous beam bridge constructed by cantilever are studied in this paper. The main research work and results are as follows: 1) the finite element model of Gaoyuetang Bridge is established by using Midas/Civil2010 software, and the safety of bridge structure design is verified by PSC checking calculation. 2) the design elevation, pre-arch degree, construction pre-arch degree and hanging basket deformation of the Gaoyuetang Bridge are studied, and the elevation and control methods of the formwork in the early stage of the Gaoyuetang Bridge are obtained. Thirdly, the construction safety risk assessment of Gaoyuetang Bridge is studied, and the corresponding safety measures are put forward. Based on the Gaoyuetang Bridge, this paper studies on the structural safety, construction safety control and construction safety risk assessment, which has practical guiding significance for the safety construction and management of the Gaoyuetang Bridge. At the same time, it can provide a reference for the safety construction and management of the prestressed concrete continuous beam bridge with cantilever pouring method.
