Shear Strength Properties of Decomposed Granite Soil in Korea
Since decomposed granite soil shows various characteristics of shear behavior dependent on initial conditions such as weathering degree and grain breakage, it is necessary to investigate changes of shear characteristics for different initial conditions. Direct shear tests and triaxial compression tests(¯C¯U, CD) were carried out in this study for undisturbed and compacted decomposed granite soils obtained from 3 construction work sites with the various weathering degree and components of parent rocks. Regardless of degree of weathering, the deformation behavior of undisturbed samples under low confining stress become hardening to softening as overconsolidated clay. Whereas compacted decomposed granite soils did hardening-constant as sedimentary clay. In CD tests for undisturbed samples, it turns out possible that strain increment ratio( dυ/dε) is expressed as linear form α(M – η), i.e. dυ/d ε = α(M – η).
