Abstract:

The reinforcement mechanism and the ultimate compressive strength formula of soilbags in 2D space are reviewed; and the deficiency of the formula is also highlighted. The reinforcement mechanism of soilbags in 3D space is suggested; and two ultimate compressive strength formulas of soilbags under complicated stress situation are derived, which are based on the extended von Mises criterion and the Lade-Duncan criterion respectively. The new formulas are successfully used to predict soilbags’ compressive strength; and their values are verified to be much more close to the experimental measured values from compressive tests on soilbags compared to the values calculated from the 2D strength formulas.

Key words: soilbag, extended von Mises criterion, Lade-Duncan criterion, ultimate compressive strength
