clay soil cohesion (c) and clay undrained shear strength (Su)

WebWe assumed that soils with a high sand content have much lower cohesive forces and a different pore-size distribution compared to other (fine grained) soils. Therefore, texture is a main factor determining aggregation, soil type, and cohesion. Under extreme vertical compression, cohesion behaves differently in silt and clay soils than in sandy ... WebSep 26, 2024 · where c s is the cohesion force (kN/m 2); α is the cohesion force coefficient; and c u is the cohesion force in undrained conditions (kN/m 2). The α value varies depending on the hardness of the clay layer, the type and construction method of the pile, the stratum condition, and the size of the pile. diag on can プロトコル
