1. Use of the dilatometer reduces labor and time outlays by a factor of approximately 10-15 as compared with plate tests, and makes it possible to determine the compression modulus at a depth to 30 m. In addition to other indirect methods, this method is recommended for engineering surveys of quaternary silty-clayey soils exhibiting isotropic properties, irrespective of their genesis and consistency, 2. When the dilatometer is used for surveys, it is necessary to obtain no less than six compression-modulus determinations foe each engineering-geologic horizon to evaluate the soil's inhomogeneity, and to process them statistically to determine the average (normalized) E value for a coefficient of variation of not more than 0.3 in conformity with the requirements set forth in GOST 20522-75. The average value obtained is then introduced to the correlation equation corresponding to soil conditions similar to those in the surveys. [ABSTRACT FROM AUTHOR] |
