摘要
灰土挤密桩应用广、既经济又方便,是处理湿陷性黄土最有效的桩之一。对湿陷性黄土、灰土挤密桩作了简单介绍,详细阐述了桩孔填料的配置和选择,通过前人的室内击实试验分析了含灰量和含水量对灰土挤密桩处理效果的影响,并对其进行定量分析,最后总结得出最大干密度、最优含水量、水灰比与挤密效果之间的关系,并提出一些建议。
Lime-soil is applied in construction widely,and is a convenient, economic and effective method of dealing with collapsible loess foundation. Thus, this paper has a further discussion about the mechanism and basic characteristics of lime-soil and lime-soil foundation. Firstly, this paper introduces collapsible loss, lime-soil pile; secondly, it analyses the influence of efficiency with different lime content and water. Then,a quantitative analysis is held for the effect of limesoil pile on collapsible losses. Finally, this paper provides several suggestions and conclusions.
