适用范围:This standard (Part II) covers the procedure of dynamic driving of a 62·5 mm cone and thereby obtaining a record of resistance of the soil. The cone is directly driven into the ground and for eliminating the friction on the driving rods bentonite slurry is used. The use of bentonite slurry may not be necessary when the investigation required is up to a depth of 6 m only.
