Take a Detailed Look at the Practice of Drystone Retaining Wall Construction: Drystone retaining walls make very efficient use of local materials, and sit comfortably in their environment. They make an important contribution to heritage and to the character of the landscape, and are loved by many people who value the skill and ingenuity that has gone into their construction, as well as simply how they look. And yet, in engineering terms, they are complex. They can deform significantly as their loading changes and their constituent stones weather. This gives them ductility—they deal with changes by adapting to them. In some ways, they behave like conventional concrete retaining walls, but in many ways they are better. They cannot be designed or assessed correctly unless these differences are understood.
    Implementing concepts that require no prior knowledge of civil engineering, the authors: Explain the behavior of earth retaining structures + Provide a theoretical framework for modeling the mechanical stability of a drystone retaining wall  + Outline reliable rules for constructing a drystone retaining wall  + Include charts to support the preliminary sizing of drystone retaining walls  + Examine the relevance of drystone in terms of sustainability  + Describe more advanced methods of analysis.

    Dry stone retaining structures are structures made of individual decimeter stone blocks in contact. One advantage of this construction technology lies in the weak amount of embodied energy required for their construction, and uses only local materials. This technology may be a positive answer to the challenges brought by sustainable policies in civil engineering.

    Many of these structures are older than one hundred years and sustain damage due to ageing; this places the owners in front of a challenging issue. Usual scientific tools cannot address the specific behavior of such structures. Due to the discrete nature of the system, a large amount of energy can be dissipated at contact level before failure of the structure. The shape, arrangement and possible breakage of blocks may play a major role in their overall behavior, specific to these structures. This book brings an overview of the DEM technique to model the behavior of discrete civil engineering structures. Physical models, modeling and site measurements are all explored, helping the civil engineer evaluate the behavior of unique structures.

    The only DEM technique to model the behavior of discrete civil engineering structures + A specific and sophisticated tool to address the general features observed on site + Details physical models, modeling and site measurements.
