In the traditional research of slope stability, it is difficult to continuously obtain the moisture content of soil in long time sequences.
In combination with the precipitation, temperature, and vegetation cover data in the study area, the variable infiltration capacity hydrological model is used to estimate the daily variation of soil moisture content, which is used as a calculation condition for the analysis of slope stability.
The results show that, from 1970 to 2010, the spatial-temporal distribution of soil moisture content in the Weihe River Basin showed an increasing trend.
Moreover, the shear strength of soil decreased, but the range was stable at approximately 2%.
The strength reduction method based on the M-C inscribed circle criterion (DP3) shows that the slope stability factor k had an increasing trend for over 40 y.
The portion of the period with a k value higher than 1.2 is more than 85% of the entire period, that with a k value between 1 and 1.2 is approximately 9%, and that with a k value less than 1 is approximately 5.5%.
The R/S analysis results show that the Hurst coefficients of the τ-t curve and the k-t curve are 0.5568 and 0.5888, respectively, and that the slope is in a state of no variation.
Based on these factors, the present and future of the slope is in a stable state.
This scheme is a method of studying slope stability based on hydrology, and it provides a modern alternative for soil shear strength calculation and geological hazard assessment.
