Abstract: |
Based on sliding plane hypothesis, magnitudes and distribution of active earth pressure under arc wall back are calculated using horizontal layer analysis method. The parametric study shows that the distribution curve of active earth pressure turns from convex curve to concave curve with the decrease in wall inclination angle. The results of arc wall back are compared with that of plan wall back for calculating magnitudes and distribution of active force. It is shown that using arc wall back can greatly reduce the value of active earth pressure and improve the stability of retaining wall against overturning and sliding for the tilt angle of wall back in a low value, the soil-wall friction angle and the internal friction angle of soil in a high value. |
