This question concerns the stability of an existing slope next to a canal after an additional 2m thick fill material is proposed to be placed on top of the existing ground level as shown in Figure 1 together with the soil properties. a. By means of manual calculation with method of slices, check the stability (overdesign factor) of the slope using Bishop simplified method. You will perform the analysis based on EC7 Design Approach 1 (DA1) using the centre and the radius of the potential slip circle assigned to you in Table 1.
