    • Abstract
  • The mode of earth pressures acting on the front wall and behind the wall plays a key role in checking the anti-overturning stability of cement-soil gravity retaining wall after excavation. The curve of anti-overturning safety factor somewhat varies under different earth pressure modes. The turning point can be determined according to the balance of vertical force. In order to consider the characteristics of wall deformation and the change of effective vertical earth pressure, a coefficient is introduced to modify the earth pressure on the wall, meanwhile a formula for calculating the safety factor is proposed under the new mode. Through analysis of the morphological characteristics of the curve and the influencing factor under three different earth pressure modes, the calculated results show that the anti-overturning safety factor is more reasonable, and the modified method can better reveal the real state of wall overturning.
