New Thinking

Due to the special mesh structure, geo-grid material can avoid local subsidence of filling material, reduce uneven settlement of soil mass to the largest degree and improve the whole stability of soil mass, so the reinforced earth-retaining wall with geo-grid is widely used in engineering. Meanwhile, researches on its dynamic characters are not enough and it is hard to judge the whole stability of reinforced earth-retaining wall under seismic condition. When unstable failure happens, the location of failure surface can hardly be identified. These disadvantages have seriously limited the development of this supporting method and cause unsafe potentials for engineering. Based on the FEM strength reduction dynamic analysis and combined with practical engineering, the paper conducts stability analysis on the reinforced earth-retaining wall of geo-grid under seismic condition and the research achievements provide a new thinking for the seismic design of reinforced earth-retaining wall with geo-grid.

Earth Retaining Structures

As an alternative to classical retaining solutions, as gravity or flexible retaining walls, the reinforced earth retaining structures are successfully used. The interaction between the reinforcement and the soil fill and their failure mode as well, are important issues to take into account for the design of these types of structures and the corresponding calculation methods used for their design. From this point of view, an important element is the shape of the failure surface, considered in the design calculation as: plane, circular, etc., which has an important influence on the tensile forces values within reinforcements. This paper presents a new theoretical method for the calculations of the reinforced earth retaining structures and the corresponding results for failure surface shape and for tensile forces in the reinforcements. Considering the similarities between the theoretical results presented in this paper and the experimental results presented in the specialty bibliography, this method creates the possibilities to design in a more economical way, only by taking into consideration the correct interaction mechanism between the soil and the reinforcements
