University of Missouri-Columbia Department of Civil Engineering Assigned: Monday 10/19/09 CE 3400 Due: Monday 10/26/09 Fall 2009 Homework #11 Rate of Settlement No. 1 1. A 30-ft-thick stratum of clay is underlain by impervious bedrock. A sand fill is placed over the clay and causes 2.6 ft of consolidation settlement in the clay. The coefficient of consolidation for the clay is 0.05 ft 2 /day. Compute and plot the surface settlement (in feet) vs. time (in years). 2. A layer of silt is 20-ft thick and is underlain by freely draining sand. A wide approach embankment to a bridge will be constructed from sandy materials. The weight of the embankment should cause an increase in effective stress in the silt of 1500 psf and ultimately result in 1.8 feet of consolidation settlement within the silt. As an afterthought, the designer suddenly becomes concerned about differential settlement between the pile-supported bridge and the embankment. The designer indicates to you that he would like to wait until most of the settlement has occurred before finishing the grading and paving.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
