Geo-Tec B allows the verification of stratified slopes in the presence of water beds and loads.

Work begins by inserting geotechnical parameters with Geo-Tec A or other methods. Following phases involve the definition of slope and strata geometry using the mouse. Circular or polygonal slide surfaces can be inserted and modified using the mouse. Geo-Tec B can automatically calculate a series of circles through an interpolation between two selected extreme circles.

Geo-Tec B calculates the safety coefficient for each surface using Janbu, Bishop and Fellenius methods and graphically identifies that having the lowest coefficient as the critical surface.

Strata dimensions are defined by the user but Geo-Tec B is able to perfect dimensions according to the theoretic foundations of the adopted method.

Geo-Tec B also allows an immediate verification for seismic zones using a pseudo-static method.

When using the Janbu calculation method, it is possible to apply an external force to the slope. This force is considered an increase in the resisting force (stabilizing) and not a decrease in the pushing (destabilizing) force.

Reinforced earth

Biggest novelty is its support of Reinforced Earth, i.e. slopes stabilized and reinforced with synthetic geo-grids. This is an increasingly popular technology, easy to apply, good technical results even in tricky cases – and a low environmental impact.

Immersed slopes

Another key addition is the accurate, incorporated function for dealing with immersed slopes, whether in static conditions or with simulated fast draining.

 

Pilings and retaining walls

Geo-tec B allows the user to insert pilings and retaining walls in the slope-

Variable loads: loads can be either permanent or variable. In video, these are shown as two trapezoidal diagrams on the ground profile: first, the permanent load then, above it, the variable one.
Vertical seismic coefficient: Geo-Tec B supports horizontal and vertical seismic actions.
Strata panel: The Strata Panel now contains the safety coefficient value of the critical surface.
Load situations: Geo-Tec B calculates different load situations and find the lower safety coefficient.
