In the first part of the study, consideration is given to the possible use of continuous sheet fabric reinforcement in embankments with non-vertical sides. A hypothesis for how the reinforcement functions is advanced, and design procedures are developed. In the second part of the study, the problem of cracking of earth and earth-rockfill dams has been studied. It has been recognized that the tensile strains and stresses which develop within the embankment are the main cause of cracking. This makes the knowledge of the behaviour of soil in tension necessary for adequate design and construction. Hence, a simple laboratory technique for tensile testing of soils has been developed. Furthermore, an alternative defensive measure against cracking and hydraulic fracturing by using fabric reinforcement is proposed and discussed. Laboratory work has been conducted, through shear box tests and triaxial tests, to study the feasibility of reinforcing cohesive soils (ie, clays) with fabric. Using a standard finite element program, the analysis of cracking and stability is presented in Chapter 9. This includes a study of the influence of the inclusion of reinforcing fabric sheets on the internal stability of earth embankments.
