| Research Abstract |
The cohesion is one of the strength parameters which exhibit the shear characteristic of soil. Cohesion is unrelated to normal stress. This parameter is important on disaster prevention, such as being used for slope stability analysis, but the mechanism was unclear.
Cohesion was calculated by the molecular dynamics method. The calculated value is larger than experimental measured value double digits. These results shows that expression of cohesion cannot be explained only in an electrochemical effects.
