Application of Flyash in Building Ground Treatment
-
摘要: 介绍了粉煤灰在建筑工程地基处理中的应用工程实例,通过对不同配合比的二灰土试样的物理、力学性能分析,确定二灰土垫层的最佳配合比。在现场进行了最佳配合比的压实试验。现场静载试验结果表明,该方法是成功的,具有显著的经济效益,值得推广。Abstract: A project example in which flyash is used in ground treatment is introduced.The optimum mixture ratio of lime-flyash-soil cushion is determined through the analysis of physical and mechanical properties of lime-flyash-soil samples with different mixture ratios. Field compaction test is done under the optimum mixture ratio.Field bearing tests show that this treatment method is successful.Lime-flyash-soil cushion is prominently economical and worth popularizing.
