Feasibility • Calculating Cover Thickness • Vertical stress due to circular loading • Assuming HS-20 loading • Final thickness: 2 ft. • Calculating Slope Stability • Average of cross-sections located at north and south end of canal • Liner tension must fall under 312 lbs/ft or negative.
Performance Re-graded C L Slope of 3H:1V
Performance AFTER qDESIGN=2.55 ft3/day 40% reduction of seepage • BEFORE • qCRITICAL= 4.44 ft3/day
