Aim: The aim of this study was to assess the geological engineering properties a marginal land in Borikiri Sandfill, Port Harcourt, Nigeria, using both field and laboratory investigations.
 Study Design: design involved drilling 4 boreholes standard penetration tests determine soil profile index such as particle size analysis, atterberg limits, moisture content. Consolidation triaxial were...

Vertical drains have been widely used in soil improvement projects to accelerate consolidation and improve the strength of soft soil. Previous models are mainly based on instantaneous loading, which cannot reflect actual time-variable loading condition. This paper presents a set analytical solutions for with vertical under depth time-dependent involving one-step multi-step cyclic loading. A fou...

A large-scale immersion experiment was carried out to assess the collapsibility characteristics of loess in Bu Li village located Weibei Loess Tableland, and seepage evolution were determined. The effects void ratio, natural moisture content, material composition, microstructure on characterized by X-ray diffraction, scanning electron microscopy, water-soluble salt analysis elucidate mechanisms...

To study the influence of shield excavation on surrounding soil, and to control subway tunnel surface settlement deformation buildings, it is necessary additional stress soil caused by law settlement. Combined with a construction project tunnel, this article uses Mindlin solution in elastic mechanics obtain three-dimensional calculation formulas for thrust cutter head displacement field frictio...

Several reports have documented similar efficacies and tolerable toxicities of radioimmunotherapy (RIT) consolidation and rituximab maintenance after initial R-chemotherapy of follicular lymphoma. The relative merits of these two interventions are currently under discussion. We now raise the question whether both RIT consolidation and rituximab maintenance should be used together aiming to augm...

• Errors in FOSM, when applied to consolidation settlement of clay, are quantified. Both theoretical scenarios and real case studies considered. acceptable reliability analysis normally consolidated clays. Larger errors introduced if overconsolidated multi-layer cases relatively lower than single layer problems. The ground-supported transportation infrastructures may vary greatly depending on t...

This study investigates the effect of shield tunnel grouting on excess pore pressure distributions around and ground consolidation settlement. First, it presents half-plane an unlined caused by based complex variable theory conformal mapping method. Second, analytical solution for soil is derived using transformation method Terzaghi–Rendulic. The drainage conditions lining are idealized into th...
