Questions & Step-by-Step Solutions
In a site investigation, which test is most commonly used to determine the in-situ shear strength of cohesive soils?
Step 1: Understand what in-situ shear strength means. It refers to the strength of soil in its natural state, without any disturbance.
Step 2: Identify the type of soil being tested. Cohesive soils are those that stick together, like clay.
Step 3: Learn about different tests used to measure shear strength. There are several tests, but some are more common than others.
Step 4: Focus on the vane shear test. This test is specifically designed for cohesive soils.
Step 5: Understand how the vane shear test works. It involves inserting a device with blades (the vane) into the soil and rotating it to measure the resistance.
Step 6: Conclude that the vane shear test is the most commonly used method for determining the in-situ shear strength of cohesive soils.
