【摘要】 为了证明强夯法中同能级下重锤低落比轻锤高落夯实效果好的经验总结的正确性,运用能量转化原理、碰撞理论以及空气阻力分析三种基本理论为其提供理论依据;通过分析室内模型试验所得数据,对比轻锤高落与重锤低落两种情况下土体加固程度、有效加固深度及加固效果,得出了重锤低落比轻锤高落施工效率高,加固效果好,且优势主要集中在提高土体密实程度方面,在提高有效加固深度方面的优势相对较小的结论。更多还原

【Abstract】 To prove a fact that heavy hammer with low drop distance has a better reinforcement effect than light hammer with high drop distance under same energy level,principle of energy conversion,collision theory and the analysis of the air resistance provide theoretical basis. Then,through the laboratory test data,this paper contrasts soil consolidation degree,the effective reinforcement depth and reinforcement effect of these two cases,which prove that heavy hammer with low drop distance has high efficiency and better strengthening effects,and advantages mainly concentrated in the aspect of improving soil compaction degree,advantage in improving the effective reinforcement depth is relatively small.更多还原
