“…The piles were tested in dry sandy soil. This assumption has been made due to the fact that the capillary zone in sands is a relatively small, and thus is considered a lesser significance degree and can be ignored (Józefiak et al, 2015). The piles were driven in a large calibration chamber with internal dimensions are (900mm x 900mm x 1200mm length) and a wall thickness of 18mm.…”

“…The velocity responses can be calculated by integration. The dynamic stiffness can be obtained by (1). In order to ease the wave reflection on the steel plate of the sand box, five polystyrene foam cushions with a thickness of 0.02 m were installed on the bottom and four sides of the sand box ( Figure 2).…”

“…Two different types of capacity are needed to distinguish: one is ultimate bearing capacity which is usually controlled by the pile strength and the other is service capacity which is usually controlled by the pile settlement. For most friction piles designed as railway bridge foundations, the service capacity is paid more attentions and is determined by the maximum settlement of the pile head [1]. Static load test (SLT) is a reliable method to evaluate bearing capacity of pile foundations [2]; nevertheless, SLT cannot be employed for testing existing bridge piles in service.…”

In order to investigate the applicability of dynamic stiffness for bridge cap-pile system, a laboratory test was performed. A numerical model was also built for this type of system. The impact load was applied on the cap top and the dynamic stiffness was analysed. Then, the effect of the effective friction area between pile and soil was also considered. Finally, the dynamic stiffness relationship between the single pile and the cap-pile system was also compared. The results show that the dynamic stiffness is a sensitive index and can well reflect the static characteristics of the pile at the elastic stage. There is a significant positive correlation between the vertical dynamic stiffness index and bearing capacity of the cap-pile system in the similar formation environment.

“…As one of the classical stability problems in soils mechanical, the foundation bearing capacity has always been the focus of scholars and engineers. In recent years, many scholars have devoted themselves to the ultimate bearing capacity and deformation of pile foundations [2][3][4]. In permafrost regions, shallow and deep foundation are the two commonly used types.…”

This paper presents a study on the ultimate bearing capacity of circular shallow foundation in frozen clay. The bearing capacity were determined by model test, numerical simulation and analytical solution. In numerical simulation, the temperature field considering the phase transition was transformed into a temperature load and applied to a three-dimensional solid model. The generalized Kelvin model was used to describe the creep of frozen clay, and step loading was used. Based on the tests results that frozen soil fails because of local shear, we proposed an analytical model to estimate the ultimate bearing capacity of circular shallow foundation with local shear failure mechanisms. Based on the limit equilibrium theory, it was assumed that the fracture plane of the model only develops to the boundary between the transition zone and the passive zone. The results from present study and some other method are presented and compared, which has shown and verified the feasibility of our method. And the analytical solution is in good consistent with the results of the model test and numerical simulation.
