高温多年冻土地区大口径钢波纹管温度场分析及钢波纹管涵洞应用效果

摘要

Based on the actual investigation data of the national highway 214 different sections of the corrugated steel pipe culvert,analyzed the actual application condition and part of the steel corrugated pipe culvert temperature change. The results show that the steel corrugated pipe culvert in use along with the changes of the surface environment and climate conditions appeared respectively deflection, corrosion, jam and subgrade and pavement damage condition and so on, at the same time due to the high temperature permafrost regions of large temperature changes fast lead corrugated steel pipe culvert have great influence on the subgrade soil. This paper mainly discusses in ensure the normal use of corrugated pipe culvertand ecological diversity at the same time.%基于214国道不同路段的钢波纹管涵洞的实际勘测资料，对沿线的钢波纹管涵洞的实际应用状况以及部分钢波纹管涵洞的温度变化状况进行了分析。结果表明钢波纹管涵洞在使用中随地表环境以及气候条件的变化分别出现了弯沉，锈蚀，堵塞以及路基与路面的破损状况等等，与此同时由于高温多年冻土地区的气温变化较大较快导致波纹管涵洞对路基土产生较大影响。本文主要讨论在保证生态环境多样性的同时，保证波纹管涵洞的正常使用。
