Shear Box Test Lab Report

Calculations and graphsUse your textbook chapter 10 as a help to do this shear test calculations.Develop a table for calculation of vertical strain, horizontal strain, vertical stress, horizontal stress during shearDraw the graph of time versus vertical displacement for all consolidation stages in one graph.Draw the graph of horizontal stress versus horizontal strain during shearing and calculate the maximum dilation angle (if exists) and determine the peak shear strengthUse the results from other group and your own group to draw the graph of vertical stress versus failure shear stress (at that specific vertical stress) and determine the cohesion (if exists) and internal friction angle of the soil.What is the type of behaviour of your testing soil? Dense sand or loose sand? Explain why?Calculate the internal friction angle at critical state for your soil (see chapter 10)Which internal friction angle is safe to take for your soil to design your structure on this soil?In your test results negative vertical displacement is meant as expansionYou dont need to write down test procedure and answers to above questions are enoughUse excel data sheet to submit your answers.
