Determinação da Pressão
A janela "Determinação da pressão" permite introduzir a profundidade da superfície de deslizamento e a carga atuante na estaca anti-deslizante acima da superfície de deslizamento.
Active horizontal force acts behind the pile and it is defined as follows:
- residual active force - the magnitude can be changed in subsuquent stages
- active pressure
- input pressure distribution - the overall pressure on the pile above the slip surface is defined in the table, passive horizontal force is not defined anymore
Passive horizontal force acts in front of the pile and it is defined as follows:
- residual passive force - the magnitude can be changed in subsuquent stages or automatically calculated according to the excavation in front of the pile
- springs
Active and passive residual forces can be calculated in the "Slope stability" program and transferred into the program "Anti-Slide Pile". Next, the shape of the pressure distribution must be specified. Program does NOT INCREASE the input passive and active force by any partial factor during the analysis - it is necessary to determine them according to required standards and rules.
Se as forças forem obtidas a partir do programa "Estabilidade de Taludes", estas estão de acordo com o método de análise definido no programa. Por exemplo, se a análise for realizada de acordo com o Eurocódigo EN 1997-1, os valores obtidos para as forças correspondem a valores de dimensionamento.
