通过对某铁路专用线软土地基工程勘察,查明了该路基软土属于新近沉积土,针对新近沉积土的工程特征提出了路基处理建议,为该工程基础设计提供了依据。并通过与工程实践对比分析和总结,为类似软土地区路基工程勘察提供借鉴。 Through the investigation of the engineering of soft soil foundations on a special railway line, it is found that the soft soil in the roadbed belongs to the newly deposited soil. Based on the engineering characteristics of the newly deposited soil, the subgrade treatment suggestions are proposed, which provides the basis for the foundation design of this project. Through the comparison and analysis with the engineering practice, this paper provides a reference for the engineering survey of subgrade in soft soil area.
