在标准贯入度达到60击以上的较厚极密实砂土地层沉桩时，受船机设备性能限制通常会采用冲水沉桩等施工工艺，而配备D-180柴油锤的“葛飞腾2”超大型打桩船合理利用船机性能，采用动态控制锤击过程的施工方法可以直接穿透此类地层，效果良好。
在標準貫入度達到60擊以上的較厚極密實砂土地層沉樁時，受船機設備性能限製通常會採用遲水沉樁等施工工藝，而配備D-180柴油錘的“葛飛騰2”超大型打樁船閤理利用船機性能，採用動態控製錘擊過程的施工方法可以直接穿透此類地層，效果良好。

Pile jetting construction technology is usually used when sinking piles in the thick and dense sandy soil with the normal penetration above 60 due to the limit of the ship machine equipment performance. The super-large pile driving barge "Gefeiteng 2"equipped with D-180 diesel hammer can directly penetrate this kind of stratum by reasonably using the performance of the ship machine and construction technology of dynamic control of hammering process, and its effect is good.
