Distribution of Pressures Above the Slip Surface
The distribution of load applied to an anti-slide pile above the slip surface is determined from the magnitudes of forces P and T. Constant, triangular or trapezoidal distributions are considered (for "Anti-Slide Pile" program the distribution of active and passive forces is introduced in the " " frame). For the passive (resisting) force P can also be considered a parabolic distribution, which is approximated for the simplification by combining triangular and trapezoidal part.
Types of distribution of load above the slip surface applied to an anti-slide pile above slip surface
Recommendation for active force distribution
- Triangle distribution - the layers above the slip surface are made from gravel or sand
- Rectangular distribution - the layers above the slip surface are made from fine grained soils (clay, silt)
- Trapezoidal distribution - the layers above the slip surface are made from different types of soils
