强夯施工的强夯夯击出具是按现场试夯得到的夯击击数和夯沉量关系曲线来确定，下边小编来为您进行相关介绍：

The issue of dynamic compaction for dynamic compaction construction is determined according to the relationship curve between the number of compaction and the amount of compaction settlement obtained from the on-site trial compaction. The following is a brief introduction for you:

*后两击平均夯沉量不宜大于下列数值：单击夯击能*小于4000kN·m时为50mm；夯击能为4000～6000kN·m时为100mm；夯击能大于6000kN·m时为200mm，夯坑周围地面不应发生过大隆起;不因夯坑过深而发生起锤困难。强夯置换夯击击数；按现场试夯得到的夯击击数和夯沉量关系曲线确定；

*The average tamping settlement of the last two blows should not be greater than the following values: when the tamping energy * is less than 4000kn · m, it is 50mm; 100mm when the tamping energy is 4000 ~ 6000kn · m; 200mm when the tamping energy is greater than 6000kn · m, and the ground around the tamping pit shall not have excessive uplift; It is not difficult to lift the hammer because the tamping pit is too deep. Number of blows of dynamic compaction replacement; It shall be determined according to the relationship curve between the number of tamping blows and the amount of tamping settlement obtained from the field trial tamping;

1.墩底穿透软弱土层，且达到设计墩长;

1. The pier bottom penetrates the soft soil layer and reaches the design pier length;

2.累计夯沉量为设计墩长的1.5～2.0倍;

2. The cumulative tamping settlement is 1.5 ~ 2.0 times of the design pier length;

3.Z后两击的平均夯沉量不大于强夯的规定值。

3. The average tamping settlement of the last two blows shall not be greater than the specified value of dynamic compaction.

夯击遍数一般采用点夯2～3遍，对于渗*性较差的细颗粒土，必要时夯击遍数可适当增加。Z后再以低能*满夯1~2遍，满夯还可采用轻锤或低落距锤多次夯击，锤印搭接。

The number of tamping passes is generally 2 ~ 3 times. For fine-grained soil with poor permeability, the number of tamping passes can be appropriately increased if necessary. After Z, the full compaction shall be conducted for 1 ~ 2 times with low energy * and the full compaction can also be conducted with light hammer or low drop distance hammer for many times, and the hammer marks shall be overlapped.

（1）作用加固表层土，即加固夯点间未压密土。

(1) It is used to strengthen the topsoil, that is, to strengthen the uncompacted soil between tamping points.

（2）夯击能*满夯单击能可选用500～1000kN·m，每点击数5～10击，并控制Z后两击夯沉量，宜小于3～5cm。

(2) Tamping energy * full tamping energy can be 500 ~ 1000KN · m, with 5 ~ 10 blows per click, and the tamping settlement after Z should be controlled, which should be less than 3 ~ 5cm.
