青山嘴水库一期基础工程强夯效果分析

以青山嘴水库一期基础工程为具体实例,研究了强夯处理在增加重型动力贯入10 cm最小击数、提高地基承载力、增加干密度以及降低含水率等方面的效果.通过对试验测定的相关数据分析表明:强夯能使重型动力触探贯入10 cm最小锤击数增加417.46%～600%,地基承载力提高119.44%～163.98%,土体干密度增加7.18%～8.23%,土体含水率下降4.93%～45.14%,说明强夯效果非常显著.

Effect of dynamic compaction on the first phase foundation engineering of Qingshanzui Reservoir

As the first phase foundation engineering of Qingshanzui reservoir for the concrete example,this composition discussed the effect of dynamic compaction on adding the minimum number of heavy power penetration in 10 cm,improving the foundation bearing capacity,increasing the dry density and reducing the moisture content of soil etc.The results showed that the effects are very obvious for dynamic compaction which could add the minimum number of heavy power penetration in 10 cm 417.46%～600%,and improve the foundation bearing capacity 119.44%～163.98%,and increase the dry density 7.18%～8.23%,also,reduce the moisture content of soil 4.93%～45.14%.
