Design and calculation of dry stone walls

Engineer-moderately sized dry stone masonry

Many people imagine small, relatively unstable structures of rural culture under dry-stone walls, similar to that seen by terraces or free-standing walls of pasture here. A construction technique that won't compete with our modern time and the current technical requirements can. dry-stone walls is dry stone walls for they are grown but also large loads and can be dimensioned in terms of engineering.

Examples:

Numerous dry masonry retaining walls bear today Rail Trail Switzerland

The large brick constructions of avalanche in the Swiss Alps protect still today villages, roads and railway lines.

Come this dry brick structures dating from the late 19th century, as built in the industrial revolution-new, larger roads and little later also railways across the Alps. Because cement and concrete had just been invented and transports in the difficult-to-reach terrain was almost impossible, and they were instructed to use the stone in-place as a building material. The numerous retaining walls, which were necessary in the construction of road and railway line, were built as a natural stone walls, often as mortar masonry, where possible but also as a dry masonry.

The origin of the engineering dry walls probably originates from the time of the Enlightenment, as in France, military engineers expanding the theoretical foundations of traditional construction techniques using new mathematical methods. At that time, roads had to be built to move the large armies, which stood up to the weight of the guns transported with. The quality of such buildings was no longer left to chance, but in guidelines and building codes set.

Today are to receive major efforts underway this tradition alive and to revive.

As a research project, running in France the retaining walls of dry stone masonry undergoing static tests. This project aims to establish dry stone masonry as a "normierbare" construction.
