摘要
Abstract
A structural system of triangle steel frame and suspension continuous girder bridge has been adopted in the design of Wudu Bridge in Fangshan district.The cross steel box has been designed to be main tower interface.The transitional form on height and width of variable cross-section is followed by linear variation theory,in which the total height is 35m and composing a ＂W＂ shape together with ＂V＂ shape piers.The steel towel is hoisted by 11separated segments.We have made a deep study on the prefabricate,preservation,hoisting temporary kickstand fixing and hoisting of steel tower because of the challenging construction technology and the high requirement on quality and precision.Moreover,the key technology on important and difficult points used in the whole steel tower construction is also proposed.关键词
