摘要
疏干孔在铁路粉质黏土填料路基冻害治理方面的应用还不多见。本文结合兰新铁路路基冻害整治工程实例,对路基冻害原因进行了分析,对疏干孔在抑制路基冻胀等方面的原因及效果进行了分析和研究,取得了较好的冻害治理效果,为其在今后该领域的推广应用提供依据。
The dewatering holes has been rarely applied in improving freezing treatment of the railway sub-grade.This paper analysis the reason and effect of restraining the frozen damage of subgrade,which according to the projects of subgrade frozen damage of Lanzhou-Xinjiang railway,achieved good frozen treatment effect,provide a basis for its extension and application in this field in the future.
