黄泛区水泥改良粉砂土工程性质试验及施工工艺

Engineering Property Test and Construction Technology of Cement-improved Silt in the Yellow River Flood Area

为研究黄泛区水泥改良粉砂土的工程性质及在市政道路的应用特性,文章提出对水泥掺量分别为0、5%、6%、7%的黄泛区粉砂土进行击实试验、渗透试验、无侧限抗压强度试验及扫描电子显微镜试验(SEM),并探讨黄泛区水泥改良粉砂土施工工艺。研究结果表明,黄泛区水泥改良粉砂土具有良好的工程性质,通过改进施工工艺,能够满足工程质量要求,显著提高工程经济效益。

In order to study the engineering properties of cement-improved silt in the Yellow River flood area and its application characteristics in municipal roads,this paper proposes to carry out the compaction test,penetration test,unconfined compressive strength test and scanning electron microscope test(SEM)on silt with cement content of 0,5%,6%and 7%in the Yellow River flood area,and discusses the construction technology of cement-improved silt in the Yellow River flood area.The research results show that the cement-improved silt in Yellow River Flood Area has good engineering properties.By improving the construction technology,it can meet the engineering quality requirements and significantly improve the engineering economic benefits.
