Most of the hydraulic structures are founded on permeable foundation. There is, however, no procedure to fix the basic barrage parameters, which are depth of sheet piles/cutoffs and the length and thickness of floor, in a cost-effective manner. Changes in hydrological and climatic factors may alter the design seepage head of the hydraulic structures. The variation in seepage head affects the do...

Reinforced concrete (RC) Pile cap, a thick reinforced block, is constructed to provide connection between structure and multiple single piles. In the existing design methods, behavior of RC pile cap usually considered as rigid body resulting forces or reactions on piles are assumed equal. However, in actual conditions, there possibility bending un-equal This study represents detailed finite ele...

Abstract Aiming at the situation that bottom of pile foundation contains sediment defects, theoretical analysis vertical bearing characteristics is carried out. Based on load transfer mechanism pile-soil system and based function elastoplasticity soil side weakening trifold line end pile, a calculation model for bored cast-in-place piles with slag defects under different conditions was establis...

The tandem compound piles are a combination of granular column in the deep section and concrete pile shallow section. This method effectively utilizes consolidation densification effects column, as well cementation strength material. acts path, aiding surrounding soil. On other hand, prevents bulging deformation that commonly happens columns during field construction. To study bearing capacity ...

a simplified approach for nonlinear analysis of the load-displacement response of a single pile and a pile group is presented using the load-transfer approach. a hyperbolic model is used to capture the relationship between unit skin friction and pile-soil relative displacement developed at the pile-soil interface and the load-displacement relationship developed at the pile end. as to the nonlin...

A mathematical model for an outer soil, multi-defects pipe pile, and inner soil dynamic interaction system is established to research the influences of on vibration a pile. The impedance pile deduced by applying Laplace transformation method recursive technique. Then, velocity response at head further obtained using inverse Fourier transform method. Moreover, parametric analyses are conducted t...

Pile foundations are used to support both vertical and horizontal loads in many geotechnical projects, such as coastal offshore engineering. In this project, the Finite Difference Method is proposed solve differential equation governing lateral axial pile response. Initially, behaviour of subjected load will be analysed. The effect various parameters like head fixity, cohesion surrounding soil,...

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...

Impact pile driving is a multi-component problem which is associated to multi-directional ground vibrations. At first, vibration is transferred from the hammer to the pile and then to the common interface of pile and soil. This is then transferred to the environment and has great impact on the adjacent structures, causing disturbance to residents and also damage to the buildings. It is of high ...
