What is SMARTPT?
SPT field testing is frequently used in soil mechanics – foundation engineering applications. The obtained SPT hit numbers are corrected by considering the energy differences in the hammer system used. SPT hammer monitoring mechanism was developed by Geodestek R&D engineers operating within the body of METU Teknokent, using local resources. Uncertainties up to the order of twice in the number of hits obtained by using this mechanism have been eliminated. Geodestek can accurately measure and report the energy efficiency of all types of SPT hammers within minutes, with its SPT hammer energy monitoring mechanism, with the measurement service it provides at its head office or on-site, depending on the preference of geotechnical service providers.
5 Reasons to Measure SPT Hammer Energy Efficiency
- Turkey Building Earthquake Regulation (2019); It provides an approximate range for determining the energy correction CE factor according to the hammer type from the hit numbers obtained from standard penetration tests. This range differs by almost twice, even for the automatic hammer type.
- T.R. The Ministry of Transport and Infrastructure General Directorate of Highways Department of Engineering Structures Final Report on the Preparation of Earthquake Regulations for Transportation and Distribution Facilities (2020) recommends the use of a calibrated hammer system for the selection of design-based engineering parameters.
- According to ASTM D 6066, the energy efficiency of the hammer should be known based on the measurement in the measurements taken from each site where liquefaction trigger analyzes are performed.
- Even if your hammer is automatic, the energy efficiencies obtained with different automatic hammer systems are highly affected by factors such as assembly and operation details, usage status and frequency, hammer - head - rod - sampler system connection and orientation details.
- With the standard penetration test, which is one of the most frequently used field tests, it becomes an inevitable reality to have a hammer system that you can measure and periodically control for the correct selection of parameters that will shed light on your engineering designs.
