3 cards from this section. Quick, good the night before a test.
What does c_u stand for in soil mechanics?
Consider what happens when pore pressures in soils do not dissipate.
List the three types of shear strength distributions.
Think of how strength could change from the outer parts of a cylinder to the center.
What is the purpose of the vane shear test?
Consider the soil behavior relevant during construction.
True or False: Uniform distribution of shear strength means it varies significantly from the edges to the center.
Think about how strength changes in different conditions.
Given a shear vane test where a maximum torque of 100 Nm is reached, with a triangular distribution and a soil cylinder radius of 0.1 m, how do you calculate the resisting moments?
Consider the geometry of the soil cylinder when modeling your equations.
Evaluate how varying moisture conditions would shift the expected shear strength distribution for a site and how it affects construction safety.
Research soil behavior changes with moisture content for supporting evidence.
