C and phi value of clay
The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil. The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Each letter is described below (with the exception of Pt): If the soil has 5–12% by weight of fines passing a #200 sieve (5% < P#200 < 12%), both grain s… WebIn order to make use of Equation 2.8, an appropriate correction factor must be applied (to decrease N) if a standard U.S. split spoon sampler is used without liners. The value of f, with soil plasticity (P.I. 15-60) only varies from about 4 to 6. An average value of about f t = 5 (for s u in KN/m 2) appears reasonable for most insensitive ...
