Earth statics

Earth statics are the calculation methods for the behavior of the soil as a building material and for the soil as a load on buildings , or in other words the statics of the soil.

The term earth statics is mostly mentioned in connection with soil mechanics and the foundation . Soil mechanics is the theoretical basis of earth statics, and earth statics is the prerequisite for the foundation, building in the ground. These areas merge at their borders. The calculation and dimensioning methods listed below appear again in the foundation.

The earth statics deals with:

• Active, passive earth pressure and earth pressure at rest
• Angle of friction and cohesion in the soil
• Pressure and stress distribution in the ground, especially under foundations
• Sliding and tilting security of foundations
• Stability of terrain jumps, retaining walls , sheet pile walls, etc.
• Calculation of safety against slope failure
• Calculation of the security against ground failure
• Load-bearing capacity of surface and pile foundations and other shallow and deep foundations
• Calculation of settlement and consolidation
• Percolation currents and current pressure in the soil
• Groundwater pressure and pore water pressure on structures
• Stability of construction pits
• Calculation of anchorages and grouting

Fundamentals and calculation methods of earth statics are among others:

• Mohr's circle of tension
• Slip circle calculations and slip body calculations according to Krey, Bishop , Janbu , Borowicka
• Tension trapezoidal method
• Subgrade method
• Constrained modulus method
