Part 3/8:
In the field of soil mechanics, engineers have developed simplified criteria to determine the appropriate filter design based on experimental data gathered over years. The use of such criteria allows engineers to quickly assess filter requirements without needing extensive testing for every project. Let's look at the essential aspects of this simplified filter criteria.
Gradation Curves and Their Significance
The grading of materials is characterized by a gradation curve, which shows the distribution of particle sizes in a sample. Understanding the gradation of core materials is crucial in designing filters because the particle size distribution directly influences how easily water can flow through the soil.
