| الوصف: | New concept of effective stress for unsaturated soil is proposed. It is assumed that the effective stress consists of two components. One is (σ-ua), which acts as if (σ-uw) of saturated soil and when soil is saturated, ua=uw is assumed. Another one is suction. It controls not only water content but also soil constants such as c' and mv. To prove above concept and to look into the relationship between suction and soil constants, drained (suction controlled) triaxial compression tests, including anisotropic consolidation and repeated loading, were performed on compacted Kaoline. When suction is kept constant, it seems that volume change and water content of sample are given only by the present stress state. Unified stress-strain equations were obtained using a factor α, which is defined by the new effective stress. |
