Identifying Soil Stratigraphy in Shanghai from Piezocone Soundings

Abstract:

This article presents a case history of piezocone penetration test (CPTU) of soft deposit in Shanghai. In Shanghai, stratigraphy for soft deposit is mainly obtained by the laboratory test with borehole samples. The stratigraphy identified by 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 chart proposed by Robertson (1990) is employed to identify soil layer. The results show that the Robertson charts (1990) is suitable to identify the stratigraphy of the soft deposit in Shanghai. However, there are some discrepancies of the results from Robertson charts (1990) and the norm method. Discussion on the reasons of these discrepancies is conducted.
