“…The findings indicate that the backfill located behind the wall generates the first sliding surface at the bottom of the wall heel, the second at the top of the wall heel, and the third at the top of the relief shelf. Consequently, a calculation formula for Es under the long relief shelf failure mode was proposed by utilizing the limit analysis method of a horizontal differential layer [ 24 ]. The proposed method utilizes failure surfaces to analyze the active lateral earth thrusts exerted on cantilever retaining walls.…”

This paper investigates the sliding surface failure characteristics, earth pressure distribution law and stability safety factor of inverted T-type retaining wall by using the finite element limit analysis software OptumG2, the effects of width of wall heel plate, width of wall toe plate, thickness of bottom plate, soil–wall interface friction angle, soil cohesion and soil internal friction angle of filling on the failure characteristics of sliding surface, the earth pressure distribution law and stability safety factor of retaining walls are analyzed, The stability safety factor of the retaining wall showed a gradually increasing trend as the width of wall heel plate and wall toe plate increased; as the bottom plate thickness increases, the stability safety factor of the retaining wall gradually increases; as the soil-wall interface element reduction coefficient rises, that is, the internal friction angle of the soil-wall gradually increases to the soil internal friction angle, the stability safety factor of the retaining wall gradually increases; as the soil cohesion and internal friction angle increase, the stability safety factor of the retaining wall progressively increases. The safety factor of retaining wall increases by 0.45 for every 0.5m increase in the width of the wall heel plate; the safety factor of the retaining wall increases by 0.29 when the width of the wall toe plate increases by 0.5m; for every 0.5m increase in the width of wall plate thickness, the safety factor of the retaining wall is increased by 0.62; for every 0.25 increase in soil-wall interface element reduction coefficient, the safety factor of the retaining wall increases by 0.29; for every increase of 5KPa in soil cohesion, the safety factor of the retaining wall increased by 1.16; for every 5° increases in soil internal friction angle, the safety factor of retaining wall increases by 0.6. The research is significant for studying the failure laws and stability of retaining walls and providing references for retaining wall design.

The active earth pressure acting on the rigid vertical retaining walls under translation mode has been investigated in this paper with a two-dimensional analytical method without prior hypotheses of the shape of soil arch, i.e. the trajectory of minor principle stress, which is totally different from with the existing method of combination of soil arch shape and horizontal flat-element analysis. Different emerging failure surface was compared and a parabolic surface was especially discussed in details. The proposed formula can be employed to predict the distribution of earth pressure and stresses in the failure zone. Furthermore, the analytical expression of the minor principle stress trajectory in the failure zone was derived from the stress equations. The results of the proposed analysis were compared with test data as well as the results of existing theories to validate its accuracy and applicability. The proposed distribution of earth pressure is in good agreement with the test data. Finally, a simple yet practical formulation was established to conveniently estimate active earth pressure in field.
