强夯法加固不同饱和土地基的比较试验研究

Comparative Experiment on the Dynamic Compaction Consolidation for Various Saturated Soil Foundation

摘要:

通过室内试验就中海石油炼化山东公司东营港（堆场区）场地的土性条件和加固前、加固后的变形和强度特征的变化进行了比较。此外，根据3个场地的现场实测资料的比较，分析了不同地层条件下强夯荷载作用引起的孔隙水压力的分布特征，最后研究强夯法加固饱和土地基的土性适用条件。

Abstract:

By the laboratory tests, the soil conditions of a container yard in Shandong were compared as well as the variations of ground deformation and strength characteristics before and after the consolidation. According to the comparative analysis on the field test data of 3 sites, analysis was made on the distribution of pore water pressure caused by dynamic compaction loading in different formations; and the applicable conditions for consolidation of saturated soft soil with dynamic compaction was discussed.

Key words:dynamic compaction; saturated soft soil; pore water pressure; shear strength; deformation characteristics
