Soil Mechanics Training Series Module 4 Basic Soil Properties Volume Weight Rela

Overview

This module provides definitions and equations used in solving basic soil mechanics problems. The field and laboratory measurements needed to obtain parameters for solving these relationships are also covered. A good understanding of these terms and equations is essential to the successful completion of additional soil mechanics modules.

Objectives

Upon completion of this training, participants will be able to:

  • construct a block diagram of a soil mass. From memory, label each of the nine elements with its proper symbol
  • define conceptually the most important volume-weight relationships from a list
  • select the proper equations from a given reference table to solve for unknown volume-weight terms
  • list from memory the four commonly measured laboratory parameters of a soil mass

Prerequisites

None

Duration

Module 4 - Volume-Weight Relations is a self-paced program and requires 6 - 8 hours to complete. This includes the time the participants will need to complete activities throughout the module.

Target Audience

This module series is intended for engineers, geologists, soil scientists, soil conservationists, technicians, and others needing the fundamentals of soil classification systems in NRCS
