从而得到了打桩引起的地面振动的衰减特性。
The attenuation characteristics of ground vibration caused by pile driving were proposed.
对该地基采用了强夯加固、在强夯地基上打桩、振动碎石桩和混凝土灌注桩多种地基处理方法。
The method includes the forced ram, piles driving on the ramed ground, vibrating crushed stones piles and injecting concrete piles etc.
与传统打桩锤相比较具有噪声小、无污染、振动小、打击能量高等优点，符合环保要求，并具有良好的动力学特性。
Compared with normal hammers, it has a lot of advantages, such as lower noise, no exhaust gas, less vibration, high piling energy and better dynamics characteristics.
