Sieve Analysis: The most fundamental soil test of all, is the sieve analysis. It is used to determine what type of…
Field (in-situ) Soil Tests
Visual examination: By digging trenches, test pits, visual examination can be done. Visual examination is the first thing to be done,…
Soil Testing and Measurement:
Soil properties can be measured in many ways and for a lot of different purposes, both in the field, or by…
Subsurface Investigation
In order to design the foundation of structures, we must have good understanding of the soil conditions. The first step to…
Critical State of Soil
This is a relatively new (in comparison to many decades old of soil mechanics theories) but very useful concept in soil…
Slope Stability
Natural slopes tend to slide or fall to their lower side, given long enough time. Depending on the saturation degree of…
Consolidation Settlement
Consolidation settlement is a time dependent settlement that occurs in clay soils, due to applied loads from above. As we wrote…
Elastic Settlement
After finding stresses in soil, we can calculate settlement amount. Settlement of soils in general has three stages: The immediate settlement…
