Superiority Analysis of Static Cone Penetration in Identifying Strata Interlayer in Engineering Exploration
This article takes the Rongju Lanjing community project as the research background,and explores the reliability of DCPTU in meas-uring density,identifying weak interlayers,evaluating the liquefaction potential of sandy soil,and testing the effectiveness of foundation treat-ment.The results indicate that the DCPTU method is generally consistent with the indoor test results,except for a few deviations.The DCPTU method is reliable and accurate in field density measurement.The shear strength of the cone tip resistance significantly decreases at 2 m,indi-cating weakness,while the density curve also reaches its minimum value at 2 m,further confirming the weak characteristics of the soil layer.
