| Abstract: | The test for the composite foundation of stone columns of XuSuExpressway is described in details in this paper.The tests of physical and mechanical properties,standard penetration test,dynamic sounding test,static sounding test and SASW test are taken before and after the treatments.The results are compared and analyzed,which show that the liquid potential has been eradicated when the stone columns are used to treat the soil foundation in this area.The tests and results have a value of refrecence to the similar engineering work. |
