摘　　要：以一种新型的外衬管片-内衬混凝土-输水钢管三层复合衬砌输水隧道为例,采用ABAQUS有限元软件建立精细化模型结构,研究了在外部水土压力和内部水压力作用下管片、螺栓、内衬混凝土、输水钢管的受力情况。研究表明,正常通水工况下,输水隧道结构满足承载力要求。研究结果可为输水隧道结构的优化设计提供参考依据。In this paper a new three-layer composite water conveyance tunnel with segment-concrete-steel pipe is taken as an example.Through the establishment of finite element models with the ABAQUS,the force condition of the segment,bolt,concrete,steel pipe under the external water and soil pressure and internal water pressure are analyzed.The results show that it can reduce the overall deformation of the segment under the external water and soil pressure and internal water pressure.And the water conveyance tunnel structure can meet the request of bearing capacity.The research could provide references for the structure design of the water conveyance tunnel.
