强夯碎石土地基土体结构的试验研究
摘要:通过现场容重试验和注水试验研究了碎石土地基的密度和渗透性在强夯处理前后的变化,探讨了强夯对土体结构的影响。试验结果表明:强夯能有效改善碎石土的结构,且浅部明显,随深度增加表现出逐渐不明显的趋势;强夯作用下,土体结构的改变在3m以上区域为颗粒填充所致,3m以下则为土体孔隙压缩。
Abstract:The changes of the density and permeability of the Land-based gravel in the dynamic compaction researched by the bulk density test and injection test at the scene,discussed the soil structure which effected by the dynamic compaction. The results show that: dynamic compaction can improve the structure of the gravel soil, especially superficial zone, the deeper, the more unconspicuous. Under the Dynamic compaction, the changes of the soil structure is due to the grain filling in the above 3 m,and 3m the following is due to the compression of soil pore.
