DILATOMETER EXPERIENCE IN WASHINGTON, D.C., AND VICINITY

For 3 years now, the flat dilatometer has been used to supplement standard soil borings and cone penetration tests during routine geotechnical investigations at project sites located within a 300-km radius of Washington, D.C. Although criticized for its mostly empirical nature, the dilatometer test (DMT) appears to provide very reasonable interpretations of soil properties in a diversity of geologic formations including residuum, marine sediments, and alluvium. Moreover, the DMT is an expedient and cost-effective method of profiling subsurface conditions, except in very dense or gravelly deposits where insertion is difficult. Several case histories are presented in support of these conclusions.
