【摘要】 近年来，随着我国社会经济的不断发展，交通运输事业迅猛发展，公路、铁路、桥梁等工程的建设大大增加，桥梁工程的设计与施工技术取得了巨大的进步。 本文分析了各种的桥梁施工技术，总结了其优点和不足，这些方法在施工空间狭小时，难以应用。本文提出了高低支腿龙门吊宽幅双导梁法这种新的桥梁工程施工方法。它受场地空间条件的影响较小，并研制出了与这种方法相关的一系列配套设备和措施，以保证该方法的适用性。经过实际工程(石家庄南环大桥B标段)的施工实践验证，证明高低支腿龙门吊宽幅双导梁法是一种优良的桥梁工程施工新技术。更多还原

【Abstract】 Recent years. With the development of our economy and society. It was being rapidly progressed that the traffic career. Many highways, railways and bridges were constructed. The bridge design and construction techniques progressed greatly.Many kinds of bridge construction techniques were analyzed in this paper. Their advantages and shortcomings were summarized, too. These methods are not fit to the bridge construction when the space is limited or narrow. A new technique is put forward that high-low brace gantry crane wide double guiding girder method to construct bridge. It is fit to narrow space better. And a series of relative facilities and measurement are studied and producted. So as to make itfeasible. Through a real project------"B" bid section of Shijiazhuang South Bridge. It is provedthat high-low brace gantry crane wide double guiding girder method is a good and new technique of bridge construction.更多还原
