Due to the complexity of pile–soil interaction, there is little research on active–passive piles that bear pile-top load transmitted from superstructure and pile shaft caused by lateral soil movement around simultaneously. The purpose this study analyze displacement internal force piles. Most design codes in China use elastic resistance method describe relationship between horizontal pile, but ...

In this study, a 3D numerical modelling of a single vertical drains consolidation incorporating vacuum preloading considering both vertical and horizontal drainage is presented. The effects of nonlinear soil compressibility, varying permeability and vacuum pressure distribution along the drain are examined through the dissipation of average excess pore pressure and associated settlement. A sele...

Fine-grained compressible soils are usually associated with strength challenges in the course of carrying structures, roadways, embankments, and other civil engineering facilities. In addition, due to their low permeabilities, take an awfully long duration achieve optimal consolidation, its attendant negative effects on facilities supported by soils. Engineering practitioners researchers have e...

Energy loss in a manhole as junction of storm sewers or combined is an important factor for more accurate calculation inundation. The authors formulated energy coefficients two-way and three-way circular drop manholes where one two inflow pipes are connected to outflow pipe. Since there few studies on the four-way three pipe like at intersection, we conducted experiments which with several type...

Abstract The gas storage regulations are intended to increase security of supply in winter. Tenders and direct procurement by the Market Area Coordinator should ensure that facilities filled. Both instruments can lead a displacement other volumes. Since potentially leads less allows for better control strategic behavior, it may be more effective. Tender design improved setting reserve price all...

In this paper, the free strain radial consolidation theory incorporating the changes of compressibility and permeability of the soil with the change in effective stress via time dependent surcharge preloading is presented. In contrast to the conventional analysis, the current study highlights the nonlinear characteristics of the soil during the consolidation process. A comparison of the nonline...

For several decades vibratory pile driving has been extensively applied in civil engineering, e.g. in the construction of bulkheads. On urban construction sites shock waves occur which could damage nearby building structures and annoy humans. State-of-the-art machinery provides three control inputs (frequency, excitation force and surcharge force) to achieve two almost contradictory goals: fast...
