Abstract:
Taking the examples of the treatment for a soft foundation reinforced with densification by gravel piles in Datong-Yuncheng expressway in Shan' xi province , the testing results of the composite ground is studied .The reinforcing mechanism and destroying manner for the densification by gravel pile is discussed.The in-situ testing result for the composite ground of a soft foundation is analyzed .It is found that the reinforcing method , which uses densification by gravel pile to consolidate the soft foundation , not only improves the bearing capacity , increases the strength of the soil between piles and reduces the ground settlement, but also removes and reduces ground liquefaction. The bearing capacity of composite ground, which is handled with densification by gravel pile , achieves the designing request .In particular , it will provide reference data for treating soft ground in highway construction in the future .
