Correlating Driven Pile Resistance with Drive Point Test and Measurement-While-Drilling Data

The Kansas Department of Transportation (KDOT) has commonly used driven piles as deep foundations for structure support. Standard penetration tests (SPT) and sampling have been used to obtain geological/geotechnical profiles, locate the elevation of pile tips, and estimate pile resistance before pile installation. SPT and sampling are slow and provide discontinuous data, which may not provide accurate estimation of pile tip elevation and resistance. A drive point test (DPT) consists of driving a steel rod with a solid tip into ground by repeated impact with blows (defined as a penetration index, i.e., penetration/blow) while measurement-while-drilling (MWD) refers to measuring the torque required to drill an auger into ground. DPT and MWD have recently been introduced to the practice, which are quick and can provide continuous field geological/geotechnical profiles with measured penetration indices and torque with depth. KDOT has acquired the DPT device and is in the process of acquiring the MWD equipment. However, the correlations of the DPT and the MWD data with the pile side and tip resistances are not known; therefore, it is important to establish such relationships. The proposed study is to perform DPT and MWD at selected sites that have previous pile driving analyzer (PDA) data and/or pile loading test data and then to establish their correlations.
