摘　　要：结合工程实例,对直埋热水供热管道分别采用无补偿冷安装、电预热安装方式条件下,工作钢管(直管段)最小壁厚的验算方法进行探讨,分析了无补偿设计应注意的问题。Combined with an engineering exam- ple, under the conditions that cold installation without compensation and electric preheating installation are used respectively for the directly buried hot-water heating pipeline, the checking method of the minimum wall thickness of working steel pipe （straight pipe section） is discussed, and the problems needing attention in the design without compensation are analyzed.
