Experimental Evaluation of Bearing Capacity of Single CFG Pile

2021
Nowadays, geotechnical engineers are facing the problem of soft ground, which results into low bearing capacity and excessive settlement. On contrary, cement fly ash and gravel (CFG) pile is one of the emerging ground improvement techniques, which can be applied to enhance the load carrying capacity of the soft ground.

Nondestructive Monitoring Experiments on Length of CFG Piles by GPR

Applied Mechanics and Materials, 2011
In this paper, the combination of antenna array detection method of ground penetrating radar is put forward to solve the actual engineering problem that it is difficult to monitor the length of CFG pile. The experiments of length of six CFG piles find that the relative error of the length is 5.26%.

Dynamic Response Analysis of Composition Foundation with CFG Piles

Advanced Materials Research, 2011
The dynamic time-history response analysis method was employed to analyze the dynamic response of composition foundation with CFG piles. The deformation and stress distribution of composite foundation of CFG piles with different length and amount of piles under seismic wave was investigated.

Experimental study on structural response of CFG energy piles

Applied Thermal Engineering, 2016
Abstract Energy piles have gradually emerged as a new application of ground source heat pump systems due to the heat exchange efficiency per unit length, excellent heat conductivity and low construction cost. Full-scale field tests are carried out to study the thermo-mechanical behavior of “Cement Fly-ash Gravel (CFG) piles”, a popular ground ...

Application of CFG Piles in Treatment of a Large Oil Tank Foundation

Advanced Materials Research, 2012
The original plan is to use vibro-stone column composite foundation to treat a large oil tank foundation. The result of strengthening is not satisfactory because of some factors, such as difficulty to control quality and long construction period etc. Treated ground can not meet the design requirements.

Bearing capacity and mechanical behavior of CFG pile composite foundation

Journal of Central South University of Technology, 2008
CFG pile (i.e., pile constructed by granular materials of cement, fly-ash and gravel) composite foundation is applied in subsoil treatment widely and successfully. In order to have a further study of this kind of subsoil treatment technology, the influencing factors and calculation methods of the vertical bearing capacity of single CFG pile and the CFG
