The stability checking calculation of retaining wall usually includes
the checking calculation of anti-overturning stability and anti-sliding
stability. When the foundation is weak, the checking calculation of deep
stability of foundation should be carried out.
Traditionally, the fixed value method is often used to analyze the
stability of retaining walls, but the fixed value design method can not
consider the randomness of various physical and mechanical indexes of
soil, which results in that the safety factors estimated by the fixed
value method are sufficient for some retaining walls in engineering, but
they are destroyed very quickly after being put into use. Some scholars
have done some work on introducing reliability method into the design
and calculation of retaining wall.
