Preliminary Research in Predicting Liquefaction Potential of Saturated Soil Using Vs, qc

In the paper, first describes the condition of the testing ground, then the circumstances of test (pressed wave velocity test & static cone penetration test, or vs & SCPT) is presented, i.e., the improvement of SCPT equipment make the test (Vs & SCPT) be in progress simultaneously, meanwhile, the SPT is conducted so that relations are found among the testing data. The results of tests are shown in this paper, the relative curves of sandy soil and sandy loam (Vs & N, qc & N) are gained respectively by way of analysing the test data, and experiential formulas of the curves are also acquired. In the formulas, N is replaced by N̅ (critical SPT blow count of the liquefied discriminant of earthquake Proof Code, 1989, China), and V̅s, q̅c are obtained respective. The formulas can be used to predict liquefaction potential of soils
