Thanks guys for the input. Yes, I am talking about fine grain soil soils, such as CL, CH, ML, MH. As a matter of fact, local geotech guys here in DC have been trying to convince others about whether a peak strength or residual strength values should be considered for the SOE design. Again...
Over years, I have been trying to find good resources regarding reasonable soil strength used for temporary support of excavation design, such as soldier piles with wood lagging. Most textbooks and researches have discussed permenant retaining structures, which are quite different in terms of...
