Original scientific paper In this paper, based on the overlapping deformation mode of load transfer law of uplift belled pile, and the theory of elastic mechanics, the elastic-plastic analytical solutions of uplift belled pile were derived, and the nonlinear elastic-plastic deformation analysis method was established, which made the deformation analysis theory of uplift belled pile more reasona...

In this paper, results obtained in both conventional and finite element analysis of straight and belled anchor shafts subjected to a pullout force are presented. In numerical analysis, it is assumed that no drainage takes place during the anchor pullout. Comparisons between two conventional methods of analysis for ultimate pullout load and the results obtained by the finite element analysis are...

Single piles are normally used to support the transmission tower in mountain areas. Uplift capacity of is a key factor engineering design increase stability foundation. This study numerically investigated uplift single straight and belled sloping ground which consisted clay layer underlain by medium weathered sandstone. A non-linear 3D finite element model was proposed describe behavior calibra...

The belled anchor pile has proficient application in the field of geotechnical engineering as because its enlarged base can bear more compressive loads and large volume of breakout soil within slip surface move upward under tension. The bell anchor pile can be used in case of on-land and off-shore structures where there is a threat to overturning of structures due to external tension loads. The...

We investigate how a straight skeleton can be used to approximate a motorcycle graph. We explain how to construct a planar straight-line graph G such that the straight skeleton of G reveals the motorcycle graph of M , for every given finite set M of motorcycles. An application of our construction is a proof of the Pcompleteness of the construction problem of straight skeletons of planar straigh...

Multi-belled piles are with enlarged ends; these have one or further bells at the lower third part of pile. These suitable for many soils problems such as softening clay, variation groundwater table, expansive soils, black cotton soil, and loose sand. The current study reviewed behavior belled in multi-layer subjected to axial compression pullout loading. review covered experimental theoretical...
