DD Form 1795. Combined Mechanical Analysis (Sedimentation Test)

DD Form 1795 - Combined Mechanical Analysis (Sedimentation Test) serves the purpose of conducting combined mechanical analysis of soil samples using the sedimentation test within the Department of Defense.

The form consists of sections where the testing personnel record information about the soil sample, sedimentation procedure details, test results, and calculations. Additional sections may capture sample identification, density readings, and particle size distribution curves.

When completing DD Form 1795, it's essential to accurately document the sedimentation test results and calculations. The form contributes to understanding the distribution of particle sizes in soil, aiding in engineering and construction planning.

Application Example: Geotechnical engineers are assessing the stability of a military base's slopes. By using DD Form 1795, they conduct a combined mechanical analysis to determine the soil's particle size distribution, helping in assessing the potential risks of erosion and landslides.

No additional documents are typically required for filling out DD Form 1795. An alternative form could be ASTM D422, Standard Test Method for Particle-Size Analysis of Soils, which provides guidance on conducting particle-size analysis using various methods.
