Internal Stability of Section

The internal stability of a section, examines the failure of a micropile due to buckling into the surrounding soil. The crucial step for the determination of the internal stability of the section is the calculation of the normal force N_cr that depends on the micropile length, the surrounding soil, and other effects. User can choose one of the following solution methods in the "Micropiles" tab for calculating critical normal force N_cr:

• Geometric method (Euler)
• Salas theory
• Véas-Souche theory
• CSN 73 1004 (Czech standard)
