软土地基真空预压处理工艺现场试验对比研究
|
摘要
真空预压排水工法适用于处理厚度较大的软弱黏性土层,其施工方便,作业效率高,适于大规模软弱地基加固。但排水板间距和透水通道等工艺的选择直接影响到固结效果、工期和经济费用,因此,通过现场试验,对不同工艺试验区的试验过程、试验结果进行定性、定量对比分析,以取得工法分析模式的校正参数,为将来大面积地基处理提供参考。
Vacuum preloading drainage technique is very suitable for the disposal of thick soft clay for it's convenience and high efficiency,and it's highly used in the reinforcement of soft soil foundation. But the ascertainment of plastic drainage plate distance and permeable channel affects the consolidation result, period of project and expense directly. So,the aim of this paper is to get calibration parameters of analysis model and provide a reference for the disposal of large foundation through field test and quantitative analysis of test processes and results in different test area.
