Experiences with CPTu Testing in the Indo-Gangetic Alluvium
https://orcid.org/http://orcid.org/0009-0009-0646-8118
The electric cone penetration test with pore water pressure measurement using piezocone, abbreviated as eCPTu or CPTu, is gaining popularity in India since the last 5–6 years. The geotechnical investigation activity in the country is now on the path to match up with international practices, and CPTu is one major step in this direction. An effective tool for site characterization, CPTu is being used to obtain various geotechnical parameters with high degree of reliability. The test lends economy in time and cost of investigation, and allows reliable in situ site characterization for robust geotechnical design and foundation optimization. The paper presents the authors’ experience with use of this technology as a useful tool for geotechnical investigation and site characterization. Four case studies are illustrated to demonstrate the use of the tests and the correlations that can be developed. In all the four projects, substantial savings was achieved in foundation costs by use of higher SBC values, higher pile capacities and elimination of need for ground improvement.
