This study presents an analysis of dry masonry retaining structures based on yield design theory : the structure stability is assessed using rigid block and shear failure mechanisms in the wall and its backfill. An application of this simulation on 2D scale-down brick and wood models is then addressed, showing close agreement between theoretical predictions and experimental results. Finally, the possibility of widespreading the study to periodic dry joint and dry-stone retaining structures is discussed.

“…The unit weight γ of the wall depends on the unit weight of the stones as well as the void percentage in the wall. Experimental measurements by Villemus [11,17] provides an average value of 25%, which corresponds to empirical statements. The second force acting on the wall is due to the backfill pressure p b .…”

Over the past few years, there has been a steady increase in the interest in dry-stone walling not only to preserve existing constructions but also to build new ones. Yet, no structural design method has been validated till today. In this study, a simplified model dedicated to dry-stone is propounded. This simulation, implemented in the rigorous framework of yield design homogenization, can meet engineering expectations. First, the model is introduced, and the parameter measurement detailed. Then, the validity of the method is assessed by comparisons with micro and macro-mechanical methods, and field trials. As a conclusion, possible improvements of the model are discussed.

Dry‐stone wall terrace monitoring and modelling

et al. 2018

Dry‐stone wall agricultural terraces are widespread all over the world and represent an effective retaining structure for farming purposes. However, dry‐stone walls can be subjected to degradation and damages, with complex and expensive maintenance. Such high costs are the most relevant drivers of land abandonment in many agricultural areas of Europe and of other continents, resulting in a progressive loss of cultivable surface, cultural heritages, and landscape traditional elements. Therefore, a more effective and efficient management of these systems is needed. As a contribution, in the present paper, an innovative modelling approach system is proposed. The presented model is able to describe hydrological processes on a terraced slope and to analyze the destabilizing pressures acting on the retaining dry‐stone walls in the most critical portion of each terrace. The model structure is based on the results of multidisciplinary field monitoring campaigns on water circulation in terraced landscapes carried out on a terraced vineyard (Lamole, Tuscany, Italy). A monitoring station was set up on a recently reconstructed dry‐stone wall, to measure the parameters influencing the pressures acting on the retaining structure. The results show a good capability of the model to predict the distribution and intensity of stresses on the instrumented dry‐stone wall over time and space. Such stresses were related to the earth pressure and to hydrostatic pressures (water accumulation), without the occurrence of soil saturation. Detecting the most failure‐prone portions of a terraced system, this approach can support landowners and land planners in managing these complex and fragile environments.
