Just a little more info. clay: top 3'- LL=52, PL=18, PI=34. Below 3' - LL=34, PL=17, PI=17. Consolidation testing was beyond the scope, however, the secant modulus for 1/2 peak stress from the UU tests averages about 100 ksf. Also, the vessle may only be 40' tall, 8' diameter, 140 kips (fully...
I'm looking for discussion on overturning for a mat footing. The site in question is south of Houston and has deep (30' investigated) saturated (H2O @ 3') clays with low strength. Torvane range 0.5 to 1.5 tsf., penetrometer range 0.75 to 2.5, UU's 0.6 to 1.8 tsf. The foundation is for a 50'...
