摘要：

本文从 CDM法加固海上软土地基钻孔取样的设备、具体操作及取样中应注意的一些问题出发 ,论述了在这种比较特殊的地基中钻孔取样的方法 ,这既是对我国海域 CDM法加固地基钻孔取样的经验总结 ,同时也是对“CDM法加固海上软土地基”课题在钻孔取样方面的有益探讨。

The paper presents the specific technique for boreholing and sampling in offshore soft soil improved with the cement deep mixing method(CDM)from the point of view of the machinery and equipment and their operation for the boreholing and sampling in the CDM improved soft soil and precautions to be taken during the boreholing and sampling operations.The analysis is also a summary of the experience in boreholing and sampling in CDM improved offshore soft soil in China as well as a discussion of boreholing and sampling techniques for CDM improved offshore soft soil.
