![]() Slope length model maximized factor of safetyĪs you can see from the Axes in the view, the length of the wedge is equal to the Slope Length (50 meters). Double-click in the Top panel to maximize this view.Note that, because the Slope Length (50 meters) defines a smaller wedge than the Slope Height (25 meters), the wedge size is now determined by the Slope Length rather than the Slope Height. The model should appear as displayed in the figure below: Slope length model Select the Slope Length (m) check box and enter 50.Re-open the Input Data dialog by selecting Input Data on the toolbar or on the Analysis menu.Slope Length is an optional wedge size input parameter that can be used to scale or limit the size of wedges. The wedge is very large, with a Weight of about 151 MN.Because the strength of Joint 1 includes cohesion, the Factor of Safety of this wedge depends on the size of the wedge.To re-set the wedge to the default position, right-click in the wedge and select Reset Wedge Movement in the popup menu. If you click and drag the wedge with the mouse, you can see that the wedge slides only on Joint 1 due to the orientation of the joint planes.The failure mode for this wedge ( Mode displayed in the Wedge Information Panel) is Sliding on Joint1.Double-click the Front panel again to restore the four-panel display.the height of the wedge is equal to the Slope Height we specified (25 m), demonstrating how Slope Height determines the size of the wedge. Double-click the Front panel to maximize this view.Īs you can see from the Axes on the view.Select the Joints tab to set up the strength properties of the joints.Keep the default values for all the other inputs. ![]() Slope Height in SWedge is defined as the vertical distance from the base of the slope to the crest of the slope (i.e., the line of intersection of the two slope planes). To open the Input Data dialog, select Input Data on the toolbar or on the Analysis menu. If no other wedge sizing options are specified, wedge size is determined by the Slope Height. Slope Height is set up through the Input Data dialog and is always required for an SWedge model. ![]() ![]() The first wedge size option we'll look at is Slope Height. You can also view these in the Info Viewer by selecting Info Viewer in the Analysis menu. For exact dimensions of the wedge (including Trace Length, Area, and Volume), refer to the Wedge Information Panel in the application Sidebar. Using the axes as a guide, you can estimate the dimensions of the wedge.
