This study conducted direct shear test on about 290 sorts of materials such as sandy soil, clayey soil and gravely soil to present proper standard on shear strength of soil. Before direct shear test, this paper analyzed shear strength by soil, clay and gravel in large scale and SW, SP, SC, SM, CH, CL, MH, ML, GC and GM in detail according to unified soil classification system through basic physical property test. Shear strength of soil in large scale tends to show that angle of internal friction increases as sand contents grow and it ranges 23.5°∼34.9° with cohesion of 2.0kPa∼15.7kPa.
Elastic modulus was visibly distinct by load, and which increased approximately 80% as vertical load grows. Angle of internal friction arranging 15.0°∼28.6° on clayey soil decreased as clay contents rises and cohesion increase in regular scale. Elastic modulus tends to increase initial elastic modulus with almost same growing rate. While angle of internal friction on gravel soil indicates 29.9°∼36.7° which hardly shows distinctive features.
According to test in detail, cohesion of SW, SP, SC and SM indicates small value by 94%,78% and 59% comparing to SC, SW and SP respectively. Angle of internal friction of CH, CL, MH and ML appears almost same features with ML and CL despite of 88% less value of MH. Cohesion among them varies with similar growing rate and shear strength of GC and GM is nearly identical. Elastic modulus of sandy soil is distinctive by level of load which increase by 80% as vertical load piles up while clayey soil increase initial elastic modulus with almost same growing rate.
