. A long natural slope in fissured overconsolidated clay is inclined to the horizontal with an angle =15 o . The saturated unit weight of clay is 18 kN/m3 . The water table is at the surface and the seepage is roughly parallel to the slope. A slip has developed on a plane parallel to the surface at the depth of 4.0 m. Find the factor of safety along the slip plane, for the following two cases: a. Peak shear strength parameters of clay ’=27 o c’=9 kN/m2 b. residual shear strength parameters of clay ’r =19o c’r =0

The following case study involving a failure in fissured over-consolidated clay slope was reported by Henkel and Skempton in 1954. The failure occurred in 1952 in Jackfield, Shropshire, England. The slope profile is shown in Figure 1. The failure was a translational slide where the average depth to the failure plane was 17 ft. The ground water table was very near or at the surface. The peak strength parameters of the over-consolidated clay are: cohesion, c'= 220 psf and friction...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
