Abstract:
In order to study the influence of design parameters of geocell flexible wall on earth pressure, the finite element model is developed by taking the case of wall with soil mechanics, deformation and contact information in consideration. The elasticplastic analysis of earth pressure for the retaining wall is carried out by changing the wall design parameters of thickness, slope ratio, elastic modulus, severe, cohesion and internal friction angle, etc. The results show that: the different parameters of the wall have different influences on the earth pressure and its distribution; the change of the thickness, slope ratio and elastic modulus can significantly affect the earth pressure and its distribution; the cohesion and the internal friction angle can affect earth pressure and the distribution in a certain range, and the soil pressure do not change if the cohesion and the internal friction angle is out of the range; the change of wall volume weight has little influence on earth pressure. 1 tab, 9 figs, 9 refs.
