Abstract: This paper proposes a simple analytical approach for nonlinear analyses of the load-displacement response of single piles and pile groups. Two models were adopted in the proposed approach. One model is based on a hyperbolic ...

Abstract: The uniform arrangement of pile groups widely used in practice often causes obvious differential settlement of pile foundations. To decrease differential settlement of pile groups, individual piles nonuniformly arranged ...

Abstract: Based on disturbed state concept (DSC) theory, this paper reports an analysis of the progressive failure mechanism of a pile–soil system from a new perspective. Assuming that the strengths of the pile–soil interface elements ...

Abstract: This paper gives a set of time-dependent displacement solutions for the case of a vertical concentrated force acting in the interior of fractional derivative viscoelastic soils. First, a three-dimensional fractional ...

Abstract: Excavation beneath an existing building to add a new basement is an effective mean to expand underground space that caters to the increased need of space in urban areas. Because piles serve as load-bearing structures in ...

Abstract: This paper proposes a semianalytical solution to analyze the long-term settlement of a single pile embedded in fractional derivative viscoelastic soils under time-dependent loading. In this paper, a three-dimensional (3D) ...

Abstract: To get an accurate bearing capacity of a postgrouting pile, the range of grout diffusion should be considered in practice. Considering the time-dependent behavior of power-law cement grout viscosity, calculation methods ...
