Resisting Pile Design

One of the common approaches to remediate an instable slope is installing a row of resisting piles near the toe of the slope to buttress the upper slope.  When designing a resisting pile, the engineer must know how much resisting force is required to support the upper slope.  With this resisting force, the embedment and section of the pile can then be determined.  However, the resisting force varies with the location of the pile. Most slope-stability-analyzing program will only provide a factor of safety for an entire sliding body by averaging the factor of safety of each slice; however, if a slope is divided into upslope and downslope at the location where the resisting piles are installed, the factor of safety of the upslope usually is much lower than that of the downslope.  In many cases, even though the factor of safety of the entire sliding body is lower than the required factor of safety, the factor of safety of the downslope could still be above the required factor of safety and provide supporting force to the upslope.  The design process is complicated if all of the factors mentioned above are considered.

Visual Slope greatly simplifies the resisting pile design process.  The user only needs to identify where the pile is located (by drawing the pile into the slope model), the factor of safety required for the upper slope, and the factor of safety desired for the lower slope. Visual Slope will automatically adjust the pile embedment and provide the internal forces of the pile for the section design to meet the required factor of safety of the upslope, based on the provided conditions.
