摘　　要：长输供热工程由于输送距离长,并且位于城市周边,经常会存在复杂地形问题,其中采用供热隧道穿越复杂地形越来越多的被采用。本文结合实际工程对特长供热隧道内敷设热力管道布置方案、补偿方式、管道绝热、支座绝热、安全运营等进行探讨,给出适合特长供热隧道内的热力管道敷设方案。Due to the long transportation distance and the location around the city, the longdistance heat supply project often has complex terrain,in which the heating tunnel crossing complex terrain is more and more used. Combined with the actual project, this paper discusses the layout scheme,compensation mode, pipeline insulation, support insulation and safe operation of the heat supply pipeline in the extra long heating tunnel, and gives the scheme suitable for the extra long heating tunnel.

关 键 词：供热隧道 绝热支座 管道布置 热补偿 管道绝热
