摘　　要：北溪引水主干渠为厦门市的供水主动脉,考虑到土地规划的需求以及供水升级的必要性,现对其马銮湾段进行升级改造。主干渠供水规模为16 m3/s,断面形式采用双孔钢筋混凝土箱涵。遵循断面设计需与地基适应性强,与原旧箱涵衔接方便等原则,将主干渠分为4种断面规格;并对其进行有限元计算分析,计算得出相应箱涵内力与抗浮成果。Beixi Diversion Trunk Channel is the main water supply canal of Xiamen.Considering the need of land planning and the necessity of water supply upgrading,the Maluanwan Section of the trunk canal is upgraded and reconstructed.The water supply scale of the trunk canal is 16 m3/s,and the section form is a double-hole reinforced concrete box culvert.The trunk canal is divided into four sections according to the strong adaptability of section design to the foundation,the easy connection with the old and original box culverts and the other principles.Its finite element calculation and analysis are carried out.The relevant internal force and anti-floating effect of box culvert are calculated.
