摘要:
|
通过现场试验,提出了在抽真空过程中钻孔取样技术,该技术可保证钻孔取样时膜下真空度基本不变。为真空预压法处理软土地基的深入研究,特别是在加固过程中土工参数变化和固结规律研究提供一种新的试验手段。

A sampling technology by boreholing in the process of consolidation by vacuum preloading was presented on the basis of field tests.The technology can guarantee the stability of the vacuity,so it can provide a new experimental means for further research about the vacuum preloading method,especially for the study of the variation of geotechnical parameters and consolidation theory in the process of soil consolidation by vacuum preloading.
