Book Description
In this chapter, the origin and remediation of an important sliding in the overconsolidated Boom Clay in Kruibeke (Belgium) is discussed. Local and environmental factors caused an unstable slope about 30 m deep, A larger sensitivity to erosion resulted finally in the instability of the slope. Because of the formation of fine cracks in the soil there was a possibility for the water to penetrate in the clay close to the surface, resulting in the presence of higher water pressures. Also, the presence of the excavator on top of the slope during exploitation had an important impact on the stress state of the soil. Both an analytical and numerical approach were used to estimate the factor of safety. Because of the change of the soil characteristics, the factor of safety decreases, which can be estimated through a numerical analysis (using the Strength Reduction Method). This chapter also discussed the applied techniques for the remediation using numerical analysis. Also, the importance of the field test is discussed. An integrated approach, using numerical analysis and field tests in combination, is capable of predicting the instability. This approach can also be used to evaluate the stability of the slope after remediation.

Book Description
Ten papers address both empirical and analytical aspects of clay and shale slope instability. Among the topics discussed in detail are: limit equilibrium stability analysis, shear strength of clay and clayey colluvium, use of triaxial test data to evaluate viscoplastic slope movements, numerical modeling of pore pressure distribution in heterogeneous soils, rational analysis of rainfall and landslide movement patterns, the effects of hydrothermal alteration on slope stability, mudrock durability and stability considerations, and regional clay and shale slope stability problems in Italy.

Book Description
"A slope in an over-consolidated, fissured clay was analyzed by the Swedish Method of Slices. Values of cohesion (c) and angles of friction (Ø) were determined by three different types of direct shear tests (undrained, drained and residual). Factors of safety (functions of c and Ø) indicated that the direct shear test parameter gave a factor of safety approximately four times that represented by failure conditions in the field. Drained tests gave a factor of safety nearly 2.3 times the value represented by field conditions. The conclusion is made that these two tests are of limited value for slope stability analyses in stiff fissured clays. The residual strength tests gave factors of safety values close to those represented by field conditions (1.2 and 1.1 versus 1.0 - 0.8 and 0.6 versus 1.0 for a theory modification). Further studies are required to evaluate the residual shear strength approach as a general method of analysis"--Abstract, leaf ii.
