摘　　要：结合无补偿直埋玻璃钢(FRP)/聚氨酯(PUR)保温管的受力特点,探讨了FRP/PUR保温管工作管道壁厚设计方法:通过FRP/PUR保温管环向应力初步确定壁厚,再通过校核轴向应力确定壁厚,取二者较大值作为设计值。同时,为了确保管道的整体安全性,对管道的综合应力进行了校核。Based on the stress characteristics of FRP/PUR thermal insulating pipe, this paper discussed the thickness design of FRP/PUR thermal insulating pipe. The thickness of pipe layer was preliminarily designed according to circular tension of FRP/PUR thermal insulating pipe, the thickness of pipe layer was determined by verification of axel tension, choosing the major number as the designing value. For the whole safety of pipe lines, the comprehensive tension of pipe was verified.
