Proposed Improvements To Analytical Models of Anchored Retaining Walls

Abstract

Anchored retaining walls are restraining walls constructed using anchors to achieve the highest stiffness possible within economic considerations. Anchor length estimation has an important role in the study of the stability of anchored retaining walls. The purpose of this study was to investigate the anchor length using different proposed failure models and Kranz's classic model. In addition, several parametric studies were conducted to find reliable results in the stability analysis of retaining anchored walls with the aim of obtaining stable and shorter anchor lengths. A numerical study was carried out using Geo4 and Plaxis 8.6 software on the same standard profile as analytically studied so as to validate the proposed mechanical models. The failure models proposed in this work are shown to be a useful tool for obtaining stable and shorter anchor lengths for anchored retaining walls.

Study on the Optimal Design of Anchor Retaining Wall Earth Pressure Distribution

“…After impounding, the lower soil of the slope is soaked with water, which leads to the reduction of friction angle within the soil of the slope and the possibility of landslide instability [4], so it is necessary to construct a superelevation anchor retaining wall [5]. In this paper, the inverse process of anchor retaining wall for slope excavation construction is simulated, the change of anchor shaft force in different processes is extracted [6], the soil pressure distribution after anchor retaining wall of Chinese code is compared, and the modified empirical analytical formula of soil pressure distribution of anchor retaining wall is summarized based on mathematical regression fitting method [7].…”
