摘　　要：随着城市轨道交通建设的迅速发展,可利用的地下空间越来越有限,大量新型设计方法被应用。杭州轨道交通某车站的配线区受交通、管线及古海塘等影响,无法采用常规的明挖法施工,需寻求一个合适的设计方案,以满足交叉渡线功能需求和结构受力要求。介绍了交叉渡线段的类矩形顶管法隧道断面研究过程,从建筑横断面、管节结构形式等方面对类矩形顶管法隧道的断面型式和管节结构特点进行了分析,可为类似工程提供参考和借鉴。With the rapid development of urban rail transit construction,the available underground space is increasingly limited,and a large number of new design methods have been developed and applied.Due to the influence of traffic,pipeline and ancient seawall,the conventional open cut method cannot be used in the construction of auxiliary route of a station of Hangzhou rail transit.A suitable design scheme is needed to meet the functional requirements and structural stress requirements of the scissors crossover.The research process of cross-section of quasi-rectangular pipe jacking tunnel is introduced,and the architectural cross-section pattern and pipe structural characteristics of quasi-rectangular pipe jacking tunnel are analyzed,which can provide references for similar projects.
