摘　　要：为比较单抽夯实法与脱钩强夯法两种工法对地面夯击动能的差异性,通过现场试验,采用高速摄像机拍摄同一台强夯机不同工法的各3种夯击动能的施工视频,测试两种工法不同夯击能的夯锤触底的动力加速度和夯击动能,得到了在同样夯锤和同样提升高度的情况下,单抽夯实法不脱钩夯实施工比脱钩强夯法强夯施工的夯击动能小27.4%~31.7%。试验方法和结论为相应工程提供参考。In order to compare the differences of the kinetic tamping energy on the ground between the single rope compaction method and the leaving hook dynamic compaction method,on-site tests are carried out,and a high-speed camera is used to film the construction videos of three kinds of kinetic tamping energy of the same dynamic compaction machine with different methods to test the dynamic acceleration and kinetic tamping energy of the hammer touching the ground with different tamping energy in these two methods.It is concluded that,with the same hammer and the same lifting height,the kinetic tamping energy of the single rope compaction method without leaving hook is 27.4%to 31.7%less than that of the leaving hook dynamic compaction method.The test method and conclusion provide reference for the corresponding engineering.
