DMT Application in the Investigation of Wuxi Metro

Based on data analysis of several DMT tests in the Metro Line Two of Wuxi,a proper formula was obtained in this paper for local application through combining the local soil characteristics and foreign experience.With this formula,a series of soil parameters from DMT indices could be inferred for design.And based on the data of DMT and CPT,the correlation relationship between DMT and CPT are concluded through regression analysis,least square method and regression coefficient of significance testing.These conclusions can be used for reference by the related designers.
