摘　　要：杭州文晖大桥是杭州市区唯一的1座斜拉桥。根据现场情况和斜拉桥特点,梁段采用牵索式长平台挂篮施工。牵索式挂篮能减小主梁配筋和截面尺寸,可降低工程成本;长平台式增加了挂篮顺桥向刚度,有利于控制主梁线形。通过该桥的施工实践说明该挂篮设计的总体构思及施工工艺是有效的。As the only cable-stayed bridge in Hangzhou city, Hangzhou Wenhui bridge is constructed with towing-cable long-platform suspended-wagon method based on site conditions and the features of cable-stayed bridges. The Utilization of towing-cable suspended-wagon would reduce reinforcement of girders and sectional size to cut the construction cost, while the use of long-platform would raise the stiffness of suspended-wagon along the bridge and is in favor to the control of girder alignment. The construction practice shows that the design concept and construction technique of the suspended-wagon design is effective.
