季节性冻土地区路基的水温分布和变化

摘要

Our vast land covers an area of a very broad,as is complex geological types.The highway construction and construction is of a certain negative impact.The frozen soil area accounts for 75% of the total area of the whole country,and it is more common in the northeast and the Qinghai Tibet Plateau.The frozen soil has its frost heaving and thaw settlement and cracking characteristics if you cannot achieve in the efficient processing of frozen soil. Subgrade stability will be greatly reduced.This article will start from the seasonal frozen soil characteristics and hazards to combine with the specific object of study in-depth analysis of the temperature distribution and variation of subgrade in seasonal frozen soil area.We finally puts forward our relevant suggestions to prevent subgrade frost damage in seasonal frozen regions and measures,as hopes to provide more support for the road construction in our country.%我国冻土面积占全国总面积的75％，在东北、青藏高原等地区较为多见。冻土自身具有冻胀、融沉及开裂等特点，如果无法实现对冻土的高效处理，路基稳定性将会大打折扣。从季节性冻土特点及危害入手，结合具体研究对象深入分析季节性冻土地区路基水温分布及变化，最后提出防范季节性冻土地区路基冻害相关建议及措施，希望为我国道路工程施工提供更多支持。
