The effects of elements such as tension crack (depth specified), water pressure (either phreatic surface or piezometric heads), vertical and inclined surcharge loads, and seismicity can be considered. General geometry allows for input of detailed geometry and soil profile.

The number of soils in tiered geometry is limited to three. Tiered geometry allows for quick input of up to ten-tiered slopes, each defined by its height, inclination and offset. Simplified slope allows for quick input data but is limited to three soils. Slopes are divided into three types: simplified, tiered and general. User can specify up to 25 layers of soil, each possessing different strength properties.Ĭomplex geometry can be input using mouse functions. It follows the procedure introduced by Baker and Leshchinsky, 'Spatial distributions of Safety Factors,' Journal of Geotechnical and Geoenvironmental Engineering, ASCE, 127 (2), 2001, 135-145.Įach dialog in ReSSA has its own extensive. ReSSA can display color coded safety map, a powerful diagnostic tool for assessing the stability of the slope and for optimizing the reinforcement. User can select any color for soils and reinforcements.

Elements such as connection strength generated in MSEW can be considered in ReSSA. While in Results, using the mouse right-click function, the soil properties or reinforcement details can be changed so as to facilitate design.Īn exclusion zone for slip surfaces can be specified to limit a search to ‘internal stability’, ‘external stability’, and more.ĭata files generated by MSEW(3.0) or ReSlope(4.0) can be imported to ReSSA for in-depth global stability analysis. ReSSA can analyze stability of reinforced and unreinforced slopes and embankments considering circular failure surfaces (Bishop method) and two- and three-part wedge failure surfaces (Spencer method). Here are some of the features of program ReSSA (3.0): Program ReSSA is an interactive, graphically rich program, allowing the designer to explore various design options of reinforced and unreinforced earth slopes and embankments.
