According to the engineering characteristics of reinforced embankment on soft soil

the characteristics of stability of reinforced embankment on soft soil at different times are determined and the sensitivity of stability to layers of reinforcement

inner friction angle of stiffing

and module of ground are analyzed fromtw o aspects of safety and potential sliding surface by means of strength reduction method and finite difference method. It is found that the more layer of reinforcement

the greater inner friction angle and module of ground are

and the more stable reinforced embankment on soft soil is. However

when some stage exceeds

the effect is no longer apparent . Results presented in the text will have an important reference value to practical engineering of reinforced embankment on soft soil.
