Soil arching exists in many earth structures, such as pile-supported embankments, tunnels, buried pipes, and retaining walls. These structures are sometimes subjected to surface footing loading. Limited studies showed that loading weakened active soil formed backfill material; however, this effect has not been well considered the current design. In study, two-dimensional (2D) trapdoor tests with transparent were carried out investigate development of under static The particle image...
As the petroleum industry continues to expand rapidly, X80 pipeline steel has become a key material in oil and gas transportation due its strength durability. However, welding joints, critical part of these pipelines, sometimes lack sufficient load-bearing capacity, leading structural failures. Ensuring mechanical integrity joints is essential for safe efficient operation pipelines. This study employs ABAQUS finite element analysis assess performance welded created using submerged arc (SAW)...
A combined ground-improvement method has recently been adopted for embankments on soft soil that involves the use of both deep mixed (DM) columns and prefabricated vertical drains (PVDs) to increase bearing capacity accelerate consolidation soil. well-instrumented embankment was constructed in a field using this verify its performance. Three- (3D) two-dimensional (2D) finite-element analyses were conducted evaluate performance an over improved by DM PVDs. In 2D analysis, plane-strain...
Technology of shield tunneling has been widely used in modern city subway system building, however, due to the limit urban construction land resources, it is inevitable for new building structures conflicted with existing one. Thus, essential taking correct measures guarantee safety structure. In this case, a typical case metro tunnel crossing through overpass bridge piles underpinning project studied by numerical method and site field monitoring. According structure, geological conditions...
Summary Stiffened deep mixed (SDM) column is a new ground improvement technique to improve soft soil, which can be used increase bearing capacity, reduce deformation, and enhance stability of soil. This has been successfully adopted support the highway railway embankments over soils in China other countries. However, there have limited investigations on its consolidation under embankment loading. paper developed an analytical solution for soil with SDM core pile equal or shorter than outer...
Constructing a new buried structure nearby an existing one or constructing multiple structures in close proximity may change overburden stresses, induce ground movement, and affect soil–structure interaction. Such issues become more complex when these are subjected to surface cyclic footing loading. Cyclic loading is expected have different influences on the from static This paper presents two-dimensional trapdoor tests with transparent soil investigate of versus loading, number trapdoors,...
In this investigation, six groups of cemented coal gangue-fly ash backfill (CGFB) samples with varying amounts kaolin (0, 10, 20, 30, 40, and 50%) instead cement are prepared, their mechanical properties analyzed using uniaxial compression, acoustic emission, scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy. The compressive strength, peak strain, elastic modulus CGFB decreased the content. average modulus, strain 10% amount close to that no kaolin....
To understand the mechanical properties of superlarge-diameter piles in complicated geologic conditions, authors carried out centrifuge model tests that simulated bearing characteristics single rock-socketed had different cover thicknesses and rock-socket lengths. Valuable results were obtained from tests. The overlying stratum a pile shares certain proportion upper load, so it is not wise to neglect its capacity this type design. shaft resistance tip did work synchronously with an increase...
