This study presents a multi-effect coupling model to optimize the design of geosynthetic-reinforced pile-supported embankment (GRPSE) considering effects soil arching, membranes, and pile–soil interaction on coastal highway. The developed could GRPSE fulfill construction requirements at relatively low project cost. was achieved by adjusting critical factors that govern settlement GRPSEs, such a...

Active earth pressure on retaining structures supporting a narrow column of soil cannot be properly analysed using Coulomb's theory. Finite-element limit analysis (FELA) shows that the forms multiple failure surfaces if is sufficiently narrow. This paper proposes framework for active estimation soils by combining an arched differential element method and sliding wedge method. The analytical con...

This paper is based on small-scale laboratory tests (1:10) of a rigid inclusion-improved soil under normal gravity. A low area improvement ratio (2.4%) monotonic and cyclic loading was used. 3D numerical calculations are performed to model these tests. The proposed modeling by the finite element method (FEM) using ABAQUS software. representative elementary volume suggested for reducing calculat...

Variations in the anatomical relationship of the gonadal arteries to the renal vessels are frequently reported. We present, on a male cadaver, an unusual origin and course of a left testicular artery arching over the left renal vein along with double renal arteries. The development of this anomaly is discussed in detail. Compression of the left renal vein between the abdominal aorta and the sup...

Affected by climatic conditions such as rainfall, evaporation and air temperature, most of the backfill soil is in an unsaturated state, decrease matric suction leads to failure retaining structure. In view this, this study takes vertical rigid wall with narrow research object, assuming that behind forms a circular arch considering interlayer shear stress; thus, analytical solution active earth...

Considering the limitations of terrain and engineering expenses, antislide piles are sometimes arranged in polylines. Studies show that this arrangement adversely affects mechanical characteristics piles. However, there is no in-deep understanding issue structural design calculation method have not been discussed relevant standards. Aiming at resolving shortcoming, polylines pile studied articl...

Three-dimensional numerical analyses using the discrete element method are conducted to investigate several fundamental aspects related soil-structure interaction and mobilization mechanisms in geosynthetic-reinforced pile-supported embankments. The contributions of soil arching, tensioned membrane effect, friction interaction, subsoil support, punching failure investigated. results indicated t...
