摘　　要：为研究装配整体式矩形断面双舱地下综合管廊的受力性能,采用数值分析方法对8种形式的管廊结构进行了静力分析。结果表明：不同现浇节点位置对综合管廊的承载力和应力分布有较大影响;叠合板中的钢筋桁架能有效提高结构的承载能力;侧墙与顶板之间设有支托比不设支托的结构承载能力明显提高;并讨论了各个结构形式实际施工阶段的便捷性。The finite element analysis for selected assembled monolithic concrete structures were performed to evaluate the mechanical properties of the proposed assembled monolithic concrete structures used in rectangular double cabin underground utility tunnel. The results showed that different cast of joint location on utility tunnel bearing had a great impact on the bearing capacity and stress distribution of utility tunnel; the steel-bar truss in superposed slab and the corbel between roof and side-wall could effectively improve the bearing capacity of the structure; the paper also discussed the convenience of various structures in the actual construction process.
