Three distinct material sets were identified by Huddleston-Berry as being present in the dike for <br />the purpose of engineering analysis. Table 1 shows the geotechnical data of the three material <br />types. On average, the groundwater depth is 11 ft. from the surface of the repair area and the <br />shale bedrock is encountered at 12.5 ft deep. <br />Table 1- Material Data <br /> Density (y,pcf) Internal Angle of Cohesion (c,psf) <br />Name Friction <br />Sand Gravel Soils 130 34° 0 <br />Sandy Silt, Silty Sand, <br />and Clayey Sand Soils 120 28° 0 <br />Loose Sand and Silt <br />soils 105 25° 0 <br />The material properties above were obtained from the Huddleston Berry report in Appendix A. <br />Since there are so little fines in the material, the strength is entirely based on internal angle of <br />friction. There is no cohesion in any of the three material types. <br />Tri County Dike Slope Stability Jan 08 4
