桥梁顶推施工法有着费用低廉、施工平稳的优势，能够在高桥墩、水深与山谷位置使用，也能够用于桥坡与弯桥的施工。有限单元法已经得到了半个多世纪的发展，本文主要分析了有限元在桥梁顶推施工及预应力分析中的应用。
橋樑頂推施工法有著費用低廉、施工平穩的優勢，能夠在高橋墩、水深與山穀位置使用，也能夠用于橋坡與彎橋的施工。有限單元法已經得到瞭半箇多世紀的髮展，本文主要分析瞭有限元在橋樑頂推施工及預應力分析中的應用。

Bridge incremental launching construction techno-logy has the advantages of low cost and construction smoothly, and can be used in high pier and the positions of val ey and deep water, also can be used to bridge slope and curved bridge construction. The development of finite element method has experienced more than half a century, and this article mainly analyzes the application of finite element in the bridge increm-ental launching construction and prestress analysis.
