中文摘要:

首先对滨海饱和吹填砂性土地基进行高真空击密法地基处理试验,然后对加固后的原状土进行室内试验:并根据室内试验结果分析了地基加固效果.结果表明:饱和吹填砂性土经过高真空击密加固后,干密度明显增大,含水量和孔隙比显著降低;强度指标显著提高,可满足承载力设计要求;压缩模量显著增大,且压缩模量与孔隙比存在着显著的线性关系.

英文摘要:

Field tests on the foundation treatment of saturated hydraulic fill sandy soil in costal areas were carried out by use of the high vacuum densification method (HVDM). Laboratory tests on the consolidated undisturbed soil were employed. The treatment effect of HVDM was analyzed according to the results of laboratory tests. The test results show that the treatment effect of the saturated hydraulic fill sandy soil by HVDM is remarkable: the dry density increases, the water content and the porosity ratio obviously decrease; the soil strength is greatly improved and can satisfy the design requirements of the foundation bearing capacity; the compression modulus linearly increases with the porosity ratio.
