| 摘 要： | 淤泥及淤泥质粘土形成的软土地基,具有高含水量、高压缩性和低强度等特点,须经过地基加固方能使用.深层水泥搅拌加固技术是比较有效的加固方法.目前,海上深层水泥搅拌法(CDM法)在一些地区的码头工程中得到了应用,并取得了较好的效果.为进一步认识该法,采用室内配合比试验的方法对水泥土的影响因素进行分析研究,指明各个影响因素与水泥土强度的关系,并测定其物理力学工程特性.

| Abstract: | The soft soil foundations formed by the mucky and mucky clay have the characteristics of high water content,high compressibility and low strength,which may be used only after proper improvement.The method of cement deep mixing(CDM method) is one of the effective soil improvement methods.The CDM method has been used for wharf projects in several regions and produced very good results.To further understand and study the method,factors influencing the cement-soil mixture are analyzed and studied with the labor... |
