适用范围

This International Standard specifies three methods for the determination of the bulk density of soils comprising: al 1linear measurement method D) immersion in fluid method; cj fuid displacement method. This International Standard is applicable to the laboratory determination of the bulk density of soil within the scope of geotechnical investigations. The linear measurement method is Suitable for the determination of the bulk density of a specimen of soil of regular shape, including specimens prepared for other tests. The specimens used are either rectangular prisms or cylinders with circular cross sections. The immersion in fluid method covers the determination ofthe bulk density ofa specimen ofnatural or compacted soil by measuringits massin air and its apparent mass when Suspended in fluid. The method may be used when lumps of material of suitable size can be obtained. The fuid displacement method covers the determination of the bulk density of a specimen of soil by measuring its mass in air and the mass offluid displaced by immersion. The method may be used when lumps of material of suitable size can be obtained. Iftheimmersion influid methodorfluid displacementmethod isused,andifthefluid is likelyto penetrate into the specimen (eg waten the specimen should be coated before testing to preventfluid penetration. Thebulkdensity ofa soilis useful in the determination ofthe ip situ overbpurden stress as afunction ofdepth. If reduired, the dry density of a specimen may be calculated from the bulk density and the water Content, 放known， NOTE This International Standard fulfils the reduirements of the determination of the bulk dqensity of soils for geotechnical investigation and testing in accordance withn EN 1997-1 andEN 1997-2，
