I have some particle size data that I need to plot on a graph (It is basic particle size data : clay, silt etc, no true sieve sizes). After I have my multiple curves would it be right to work out the uniformity coefficient (Cu) and curvature coefficient (Cc) from the large data set (e.g. lower...
Im the doing the FOS calculations on paper. Well the thing is the top value for the calculation came out negative because the tension crack was 15m and was assumed to be full which made W U and V quite large. Im guessing the slope failed at a much lower depth of water in the tension crack ?
The slope I'm analysing is hypothetical. I'm using the factor of safety equation which includes the presence of a critical tension crack at the slope crest(with the tension crack full of water). Does it mean the slope is completely unstable?
When I calculate the factor of the safety for a slope with a discontinuity which meets all the criteria for planar slope failure it comes out as -0.69 what does this mean ?
