The Study On Comprehensive Application Of Grave Pile And CFG Pile Combination Treating Soil

Composite foundation of dry Vibrating gravel pile and CFG pile has been widely usedin engineering construction, and has a good safety and economic practicality, whoseeconomic and social benefits are significant. Currently, its theory and design is still notperfect and mature. In this paper, the actual process will be discussed about whether dryvibrated gravel piles and CFG pile composite foundation can be a good role to explore inconstruction.Firstly, this paper introduces reinforcement mechanism and content designcalculations of the dry vibrated gravel pile and CFG pile composite foundation. Then onthe basis of the West Project Foundation Treatment of Baotou Iron and Steel Company,the foundation processed through the whole process of the construction site monitoring,dynamic master rubble with CFG two composite foundation to be processed in the wholeconstruction process the actual effect, to ascertain under different geological conditionsand different variation of the effect of ground handling constructs in CFG pile, dry gravelpile foundation bearing vibration and deformation studies, the establishment of dualcontrol of the bearing capacity and settlement of CFG dry Vibrating pile joint combinationof gravel pile composite foundation pile length optimization design model, the bearingcapacity of the gravel pile and CFG pile combination of composite Foundation, thepile-soil stress ratio and load sharing ratio analyzes and studies optimize and improve thedesign of existing theoretical foundation treatment works, the accumulated experience ofapplication development both gravel and CFG pile composite foundation.Analysis revealed that gravel and CFG pile can be used in major construction projects in complex site soil with low bearing capacity, high compression andliquefaction during earthquakes for processing. By good drainage of gravel pile foundationto solve soil liquefaction problems and reinforce high compression shallow soil,by the useof CFG pile to the deep stratum to further improve the foundation bearing capacity andcontrol the deformation, so that the treated ground has a relatively good load and seismicperformance. The composite foundation design model has achieved economic and socialbenefits in New West Project Foundation Treatment of Baotou Iron and Steel Company inthe The Composite foundation will be developed betterly in the future.
