［提要］頂推法作為一種新穎有效的施工方法，發(fā)展前景十分廣闊，但目前并沒有一套有效的仿真程序可以為頂推法施工過程提供各種必要的施工和監(jiān)控參數(shù)。以廣佛放射線珠江大橋工程為背景，研制開發(fā)了頂推施工法的仿真分析軟件BCCS。利用該軟件可以對橋梁頂推施工的整個(gè)過程進(jìn)行仿真分析，并能夠方便快捷地得到指導(dǎo)施工和監(jiān)控的各種參數(shù)設(shè)置。采用此軟件對廣佛放射線珠江大橋的頂推施工過程進(jìn)行了計(jì)算，同時(shí)還利用ANSYS軟件建立了空間模型對珠江大橋進(jìn)行空間分析，對橫向鋼束進(jìn)行優(yōu)化。通過施工監(jiān)控和成橋動靜載試驗(yàn)，驗(yàn)證了仿真分析的結(jié)果。

Abstract: Incremental launching method as a new concept and effective construction method has brightly prospects, but at present, there is no simulation program which can provide necessary construction and monitor data effectively for construction process of incremental launching method. Based on the background of the Pearl River Bridge project of Guangfo radiation, a software of simulating analysis for incremental launching construction is developed. The software can be used conveniently and fast to acquire the parameters of construction and monitoring control. The Pearl River Bridge of Guangfo radiation has been calculated by it. ANSYS is used in spatial analysis and optimization of the landscape orientation steel bundle. The result of simulation analysis has been validated by monitoring control and the dynamic and static load test in finished state.
Keywords: incremental launching method; construction process; emulation analysis; software; spatial analysis
