湿陷性土质下的公路路基施工技术探析

Highway Subgrade Construction Technology on Collapsible Soil

首先简要介绍湿陷性黄土地基的湿陷机理,并在此基础之上进一步对高速公路建设工程中的实际施工案例进行探讨,进而结合实际情况对湿陷性黄土地基的处理方案进行分析,以在一定程度上避免高速公路施工作业中因湿陷性而导致高速公路长期无法投入使用状况的出现。

This paper firstly gives a brief introduction to the collapsible mechanism of collapsible loess foundation, and based on this, it further explores the actual construction case in the expressway construction pro- jects. In consideration of the actual situation, it then analyzes the solution plan of collapsible loess subgrade, in order to avoid that expressway cannot be put into use for a long time for collapsibility in operation.
