湿陷性黄土路基施工技术分析

The Analysis of the Construction Technology of the Collapsible Loess Subgrade

随着交通行业不断地发展,公路建设项目也越来越多,在公路工程施工的过程中会由于土质等不同因素的改变而造成施工技术也有所不同。湿陷性黄土是公路施工中常见的一种地基形式,需要采取有效的施工方法才能提高其施工质量。基于此,文章通过查阅大量的文献资料,对湿陷性黄土路基处理中的强夯法,灰土挤密法,冲击碾压法,灰土和水泥土垫层法等施工方法和注意事项进行了总结和分析,,从而有效确保湿陷性黄土路基的施工质量,延长道路的使用寿命。

With the development of the traffic industry, the highway construction project is getting more and more, and the construction technology is different due to the change of different factors such as soil quality during the construction of the highway. Collapsible loess is a kind of foundation form in highway construction, and it is necessary to take effective construction method to improve the construction quality. Based on this, the authors summarize and analyze the construction methods and precautions in the treatment of collapsible loess, such as the dynamic compaction method, the lime-soil compaction method, the impact rolling method, the lime soil and the cement-soil cushion, etc. so as to effectively ensure the construction quality of the collapsible loess subgrade, In 2005, the service life of the road was extended.
