| Abstract: | In order to evaluate the liquefaction resistance of foundation soils and its influence factors,the research methods to evaluate the liquefaction resistance of foundation soils by the following three tests were reviewed in this paper: standard penetration test,cone penetration test and shear wave velocity measurement.The effects on the liquefaction resistance of foundation soils were analysed for magnitude scaling factors,correction factors for overburden pressures and sloping ground,and earthquake magnitude and peak acceleration.Discussion on the evaluation of liquefaction resistance of foundation soils by probability analysis was also made.Some results are obtained,which give a reference to the evaluation of the liquefaction resistance of foundation soils. |
