盲沟施工技术在高寒地区铁路路基施工中的应用

Application of Blind Ditch Construction Technology in Railway Foundation Construction in High-cold Areas

高寒地区铁路路基普遍存在冻融变形问题,是高寒地区铁路路基施工的难点之一。以盲沟施工技术为例,通过盲沟施工流程介绍,采用渗水盲沟的技术将路基中的水排掉,达到降低路基本体中水含量的目的,进而防止冻融作用对铁路路基形变的影响。通过实践表明,该方法在高寒地区路基施工中具有良好的应用优势,对解决冻融问题效果明显,研究成果为同类工程施工提供参考依据。

The problem of freezing and deformation of railway road foundations in high-cold areas is one of the difficulties in the construction of railway road foundations in high-cold areas.Taking the blind ditch construction technology as an example,this paper introduces the water drainage in the road foundation by using the technique of seepage blind ditch,so as to reduce the water content in the road basic body,and thus prevent and prevent the effect of freezing and melting on the deformation of the railway road foundation.Through practice,it is shown that this method has good application advantages in roadbed construction in high cold areas,and has obvious effect on solving the problem of freeze-thaw,and the research results of this paper provide reference basis for similar engineering construction.
