2012年6月12日 · Generally speaking, the ratio η F,pile of the force actually applied to the profile to the inertial force nominally developed by the eccentrics mainly depends on the vibrator-pile mass ratio M vib,dyn /M pile and on the pile-soil system boundary conditions.

2017年11月30日 · This chapter gives an overview of the different approaches available for designing piles subjected to cyclic axial loading. The behavior of piles under cyclic axial loading is, to a large extent, controlled by the response of the shaft except for very short piles.

2017年11月30日 · Summary This chapter deals with the fundamental aspects of the behavior of piles subject to axial cyclic loading. It is essentially based on the results obtained from the programs of in situ pile l...

The load bearing behaviour of such systems is presented in comparison to pile foundations and to combined pile-raft foundations. The safety concept developed in the French recommendations ASIRI for rigid inclusions is divided in two domains

2011年4月29日 · This paper describes a full-scale experiment of pile-supported embankments on soft soil, which is conducted within the French national research project, Amélioration des Sols par Inclusions RIgides (ASIRI), to provide a new design method.

2022年11月18日 · In typical designs of either stone columns or rigid inclusions, the column diameter, column length, and grid spacing are three main parameters that affect the costs and performance of the improved ground. This work is concerned with achieving an optimal design for these two ground improvement methods.

Rigid inclusions represent a further development of combined pile-raft foundations, comprising a load transfer platform between the columns and the structure. Calculation methods and design concepts are available for such combined systems in particular in France, based on measured pressuremeter modulus values and on the French recommendations ...

Institut pour la Recherche par Experimentation (IREX) is the Program Manager. Pile driving, instrumentation and testing were performed by French Laboratoire Central des Ponts et Chaussées (LCPC).

2005年12月1日 · Soft soil improvement by vertical rigid piles permits reduction and homogenization of settlements under structures. This process provides an economic and effective solution, especially when rapid construction is required. The field applications are mainly roadways, railways and industrial building foundations.

This review paper analyses key parameters influencing the behaviour of piled raft foundations, including raft size and thickness, pile diameter and length, pile configuration, and the stiffness of both raft and piles. The study provides insights into optimizing design parameters for enhanced performance and efficiency.
