Abstract EN
Taking the project of the Su-xin highway treated by using the resonant compaction method as the reference, a new method for the evaluation of liquefaction potential is proposed based on the piezocone penetration test (CPTU) and the standard penetration test (SPT).
The soil behavior type index (Ic) obtained from CPTUs and the standard penetration test index (N63.5), obtained from SPTs, are analyzed for saturated silty sand and silt.
The analysis result reveals a linear relationship between N63.5 and Ic, given by N63.5=−18.8Ic+52.0.
The larger the value of Ic is, the greater the viscosity of soil is, and the smaller the value of N63.5 is.
According to the method, liquefaction assessment of saturated silty sand and silt foundation can be conducted by using N63.5 based on the Code of Seismic Design of Building.
N63.5 is expressed by a single Ic, which is calculated from the CPTU data.
Compared with existing evaluation methods, this method can provide continuous standard penetration test values, moreover, this method involves a simple calculation, and the results obtained using the method are reliable.
