Estimation of earth pressure against retaining walls with different limited displacement modes based on elastic theory

The earth pressure acting on retaining walls due to creep and consolidation is under limited equilibrium conditions(limited displacement). Linear elastic constitutive theory can be applied to determine earth pressure distribution along retaining walls under limited displacement condition. In addition,tangent modulus in Duncan-Chang nonlinear elastic model was introduced to reflect the variations of soil modulus with confining pressure, and boundary strains were derived from Rankine active earth pressure, Rankine passive earth pressure, static earth pressure and principal stress direction deflection.According to the above four boundary strains, earth pressure on retaining walls was divided into five state zones. By comparing the calculation results obtained from the equations proposed in this paper with those of experimental tests, the following conclusions can be drawn: earth pressure distribution was always nonlinear along retaining walls for translation displacement(T mode), rotation displacement around wall base(RB mode), and translation + rotation displacement around wall base(RBT mode). Also,calculated earth pressure distributions along with the depth of wall were found to be consistent with measured values under three displacement modes.Additionally, a parametric study was carried out to evaluate the effects of internal friction angle and backfill soil cohesion on earth pressure. It could be seen from the above series of studies that the earth pressure equations derived in this work could be well applied in practical engineering in designing retaining walls.

Translation as Interpretation

This article is devoted to the study of one of the most important questions of philology—translation which throughout its centuries-long and rich history has been considered a sphere of philological activity of utmost significance providing an exceptional possibility for recoding and bringing philological and cultural traditions within the reach of people at large.Through the application of a variety of methods(linguo-stylistic,linguo-poetic,and comparative),the author attempts to study the process of translation,the clash of difficulties inevitably arising in that process,and offers solutions that will help recreate the vitality of the original and the uniqueness of linguistic thinking.Emphasis on the importance of the consideration of intra-and inter-linguistic correlations of language units in the original work of literature drives the author to the conclusion that the most reliable approach to literary translation is to be guided by the principle of“metaphoric displacement”.
