在土地整治过程中,水田类项目由于其特殊的水文地质条件,道路基础为软土地基,田间道路铺设十分困难,处理不当会出现路堤失稳、路面裂缝等病害,严重影响土地整治项目整体效果,是水田类土地整治项目的难题。为了解决水田类土地整治项目中软土地基道路的处理问题,本文以大荔县范家镇上辛区土地整治项目为研究背景,对软土地基道路铺设方法进行研究,提出一种基于对比实验的复合式砂石填埋方法,并对不同填埋厚度及砂石组合方式进行分析验证,实验结果证明了方法的有效性。
In the process of land remediation, paddy field projects due to its special hydrogeological conditions, the road foundation for the soft soil foundations, the laying of the road in the field is very difficult, improper handling will appear instability embankment, road cracks and other diseases, seriously affecting the overall effect of land remediation project , Is a paddy land remediation project problems. In order to solve the problem of soft soil foundation road treatment in paddy field land remediation project, this paper takes the land reclamation project of Shangxin District, Fanjia Town, Dali County as a research background to study the road laying method of soft soil foundation and put forward a method based on comparative experiment Of the composite sandstone landfill method, and different landfill thickness and sandstone combination method to verify the experimental results show the effectiveness of the method.
