SLOPE Cube Software Module for Slope Stability Analysis (Hydrus 2D)
The Slope Cube (Slope Stress and Stability) module was developed by Soil Water Retention, LLC as a supplemental module for the HYDRUS (2D) software package. The software simulates two-dimensional transient fields of soil moisture, soil suction, suction stress, total and effective stresses, and local factor of safety. The module is based on classical soil mechanics theories and uses the unified effective stress approach for saturated or unsaturated conditions (Lu et al., 2010). The module predicts spatially and temporally infiltration-induced landslide initiation and can carry out slope stability analysis under variably-saturated soil conditions. Transient moisture and suction fields are directly obtained using the HYDRUS-2D model, and are used to compute the effective stress field in hillslopes (Lu and Godt, 2013).
