Comparison and Analysis of Identification of Soil Stratigraphy in Shanghai between CPTU Test and Laboratory Test
This article presents a comparison and analysis between piezocone penetration test (CPTU) and laboratory test in identifying soil stratigraphy of Shanghai. In China, stratigraphy for soft deposit is mainly obtained from plasticity index and grain size distribution of borehole samples in the laboratory (refer to code method). Identification of soil stratigraphy with CPTU was developed and improved in recent decades. The analysis is carried out with the field data at test site of Yan’an Road Tunnel in Shanghai. The stratigraphy charts proposed by Robertson in 1990 (refer to Robertson charts (1990)) are used to identify soil strata. The results are comparison with that from the code method. The results show that Robertson charts (1990) can be suitable to identify the stratigraphy of soft deposit of Shanghai. Moreover, the discussion on discrepancies between them is also conducted.
