摘要

摘要: 为改善强夯处理地基的效果,针对强夯控制高填方地基不均匀沉降机理研究不足的现状,基于某工程采用强夯与分层碾压对高填方地基进行处理的结果,对强夯结合碾压控制高填方沉降的机理进行了分析.研究表明,强夯结合碾压可以提高高填方地基的各项力学指标,大大缩短达到最终控制沉降量的时间,适用于处理粘性砂土高填方地基.

Abstract: In order to improve the effect of dynamic compaction, from the present situation of the research on the mechanism of uneven high fill settlement controlled by dynamic compaction, the mechanism of high fill settlement controlled by dynamic compaction and bedded-earth rolling was investigated on the basis of a relative project and its in-situ measurement result.The research result shows that this measure can enhance the mechanical properties of high fills, and cut down the time in which high fills achieve the final controlled-settlement.Furthermore, this measure is suitable for dealing with the foundation filled by sandy clay.
