Where average stable soils are encountered, the thickness of foundation walls subject to lateral earth pressure shall conform to Table 15B for walls not exceeding 8 ft in unsupported height.


The value of lateral pressure exerted by a soil on a retaining structure that is reached when the structure yields and allows the soil to expand in a horizontal direction.


  • Mécanique des sols
  • Technique des fondations

Valeur minimale de la pression des terres, qui se produit lorsque le sol s'est suffisamment décomprimé pour que soit complètement mobilisée sa résistance au cisaillement le long d'une surface potentielle de rupture.


Les murs poids s'opposent par leur propre poids à la poussée latérale des terres. Ils subissent essentiellement dans leur structure interne des efforts de compression d'où la possibilité d'utiliser les maçonneries de briques ou de pierres ainsi que le béton non armé.
