This European Standard establishes general principles for the construction of bored piles (see 3.2). - which are formed in the ground by excavation and - which are structural members used to transfer actions and or limit deformations. This European Standard covers bored piles - with circular shape (see figure 1) and - barrettes (see 1.3 and 3.3), provided the section is concreted in a single operation. The barrette shapes covered are rectangular, T or L shaped in plan or any other similar configuration (see figure 2). This European Standard covers bored piles with: - uniform cross-section (straight shaft); - telescopically changing shaft dimensions; - excavated base enlargements; or - excavated shaft enlargements This European Standard applies to bored piles with the following dimensions (see Note) : - depth to width ratio larger or equal to 5 ; - shaft diameter : 0,3 ≤ D ≤ 3,0 m (see figure 1, figure 3 and Note); - dimension for barrettes : Wi ≥ 0,4 m (see figure 2); ratio between the dimensions : Li / Wi ≤ 6 where: Li is the largest dimension of the barrette and Wi is the least dimension of the barrette (see figure 2); - least dimension ≥ 0,3 m for precast elements used in bored piles: DP ≥ 0,3 m and WP ≥ 0,3 m respectively where: DP is the diameter of a circular precast element; WP is the thickness of a rectangular precast element; - cross-sectional area of barrettes : A ≤ 10 m² ;
