Q: In a triaxial test, what is the purpose of applying confining pressure?
Solution: The purpose of applying confining pressure in a triaxial test is to simulate in-situ conditions and assess the strength of the soil under controlled stress.
Steps: 5
Step 1: Understand that a triaxial test is a laboratory test used to measure the strength of soil.
Step 2: Recognize that soil in nature is usually under pressure from the weight of the soil above it.
Step 3: Realize that confining pressure is applied to mimic this natural pressure that soil experiences underground.
Step 4: Know that by applying confining pressure, we can create conditions similar to those found in the field.
Step 5: Understand that this helps us evaluate how strong the soil is when it is under pressure, which is important for construction and engineering.
