摘　　要：以某法兰式复合材料单杆塔工程为背景,在相同设计条件下设计了插接式复合材料单杆塔,并利用有限元软件ANSYS对其在三个典型工况下的应力、挠度和结构稳定性进行了计算分析。结果显示插接部位环向应力过大,且为结构的薄弱位置。对插接部位提出的两种补强方案进行了计算分析,结果表明对内插管采用钢内衬补强的效果比较明显。文章最后对插接式单杆塔进行了抗扭设计,提出了胶接和螺栓配合的方式防止扭转。Taking the single tower of a flange type made of composite material as study background, composite single pole of a plug-in type was designed in the same design conditions as the original project, and under three typ- ical load conditions, its stresses, deflections and stability safety factors were simulated and analyzed by FEM （finite element method） software. Results reveal that the hoop stress in the plug-in area is too large and in the weak loca- tion of the structure. Two reinforcement programs in the plug-in area were put forward and calculated and results show ： for internal intubation, the effect of using steel liners as reinforcement is relatively obvious. Finally, the sin- gle pole of plug-in type was designed for anti-torsion, and a methods of using glue and bolts to prevent the pole from torsion was put forward.
