Correlation Study of Dynamic Sounding and Standard Penetration Test Applied in Foundation Liquefaction Detection

Sandy soil liquefaction is one of cause for the destabilization of foundation soil. Based on sandy soil liquefaction principle, the methods for treating sandy soil liquefaction in China and abroad, and the mechanism of reinforcing foundation with vibro–replacement stone piles, one project located in Caofeidian area has been taken as an example to analyze the correlation between the density degrees of crushed stone piles and that of soil around piles. In addition, cone dynamic sounding test and standard penetration test have been used to summarize the effective methods for distinguish sandy soil liquefaction of similar field, the above two tests are often applied in stone pile composite foundation detection.
