영문 초록

The numerical study was conducted using the equation of Vanapallietal.(1996) related shear strength of unsaturated soils. Angle of shearing resistance(φb)and angle of internal friction(φ )appear identically in lower suction range, but angle of shearing resistance(φb) has non-linearity as suction increases. Nevertheless, the numerical study was conducted using angle of shearing resistance(φb) in even lower suction range because of limit of program function. However, behavior of real ground on applying numerical study can be analysed wrong by it. Therefore in this paper numerical analysis on applying the equation of Vanapalli et al.(1996) and φb has been compared about unsaturated slope considering continuous rainfall.
