Application of CFG Piles in Treatment of a Large Oil Tank Foundation Zhong-Qiu XIE Jun Cao Hong-Bin Xiao Zhen-Yu Li Department of Civil Engineering, Central South University of Forestry and Technology, Changsha 410082, P.R.
Engineering situation Some crude oil reservoir stage II works, the tank body’s capacity is 10×10m3, and its diameter is 80m, its height is 21.97m, and the maximum-weight is 104145t.
Considering the conditions of engineering geology and hydrogeology and engineering construction, according to the principles of safety economy and high-efficiency and feasible, and through choosing and demonstrating the cases and engineering testing, it makes sure that to adopt the method of CFG piles composite foundation.
Based on the engineering investigation report, the reason is the high water table 307# tank.
Engineering inspection found that the bearing capacity of some of the piles such as the 1209 pile of 302# tank above to 450kPa.

Energy dissipation (damping) in structures/materials at the nanoscale level, the damping/dynamics of materials require investigations before they will come to advanced engineering applications.
Introduction Structural vibrations and acoustic noise affect particularly every aspect of engineering applications [1].
The CNT-reinforced material damping phenomenon is complex because of the variety of energy dissipation/fracture mechanisms involved and there is the gap between engineering applications/structures and nanotechnology leading to the next generation engineering.
Results of research work would have wide-ranging technical benefits and direct relevance to industry in the areas of transportation (aerospace, automotive, maritime), military and civil infrastructure development.
