Calculation and Analysis of the Single Tamping Compaction Settlement Volume by Dynamic Consolidation Method

为探明强夯法单击夯沉量的数值大小,基于动能定理及文克尔地基模型,提出了强夯法单击夯沉量的计算公式,发现锤重、落距、夯锤面积等因素会对强夯法单击夯沉量产生影响。经过正交试验分析表明,落距对于强夯法单击夯沉量的影响最为显著。因此,在进行强夯法单击夯沉量设计时应优先考虑合理增大落距,以求达到经济、合理的目的。

In order to find out the value of single tamping compaction settlement by dynamic compaction method,based on kinetic energy theorem and Winkler foundation model,the calculation formula of single tamping compaction settlement by dynamic compaction method is proposed.It is found that the factors such as weight,falling distance and area of rammer will influence the compaction settlement of single tamping.The orthogonal test results show that the drop distance has the most significant influence on the click weight of dynamic compaction method.Therefore,in the design of dynamic compaction of dynamic compaction,reasonably increase the falling distance should be given priority in order to achieve economic benefits and reasonable goals.
