The design of the Gravity retaining wall (GRW) is a trial and error process. Prevailing conditions of backfill are used to determine the profile of GRW, which proceeds with the selection of provisional dimensions. The optimum section is having factors of safety of stability higher than the allowable values and stresses in the cross-section smaller than permissible. The cross-section is designed to fulfill conditions of stability, subjected to very low stresses. The strength of the material, which is provided in the cross-section remains unutilized. A computer program is developed to find stresses at various locations on the cross-section of GRW using the Finite Element Method (FEM). A discontinuity in the form of a rectangular cavity is introduced in the cross-section of GRW to optimize it. The rectangular cavity is introduced in the cross-section of GRW at different locations. An attempt is made in this paper to find the stress distribution in the gravity retaining wall cross-section and to study the effect of the rectangular cavity on the stress distribution. Two cases representing different locations are considered to study the effect of the cavity. The location of the cavity is distinguished by the parameter w, the effects of cases with varied was 0.2305 (Case-I) and 0.1385 (Case-II) are observed. The cavity, which is provided not only makes the wall structurally efficient but also economically feasible.

Reliability problem for gravity retaining wall constructed by new engineering materials is researched by using Monte Carlo probability theory, and the reliability program diagram of retaining wall is designed. Reliability calculation is programmed base on the anti-skid and anti-overturning safety failure mode of retaining wall. On the basis of known the probabilistic characteristics of the random parameters such as wall dimensions, material parameters, external load, and so on, and the program can automatically calculate the anti-sliding and anti-overturning failure probability and reliability indices. The research content and compiled program provide convenient reliability calculation method for the design of actual retaining walls constructed by new engineering materials.

New Type

A new type of gravity retaining wall combining with anchor is developed to support higher embankment. The retaining wall has the advantage of high safety, lateral deformation small, wide applicable range and low requirements for the foundation bearing capacity. The pressure distributions of gravity retaining wall with anchor have changed a lot. The change will have a significant impact on structures. In order to reveal the gravity retaining wall combining anchor pressure distributions, numerical simulation was done. The result shows that it has no obvious differences to its force state when retaining wall is reinforced with horizontal and oblique anchors, The former is applicable to the new embankment retaining wall support and the latter is applicable to the original retaining wall reinforcement.
