In the context of geo-infrastructures and specifically tunneling projects, analyzing the large-
scale sensor-based measurement-while-drilling (MWD) data plays a pivotal role in …

Understanding the relations between drilling response parameters (drilling speed, axial
thrust force and torque, etc.) and rock properties is useful to quickly acquire lithology …

Quick and accurate acquisition of the uniaxial compressive strength (UCS) of the
surrounding rock at the tunnel face effectively ensures the safety of tunnel construction. This …

This study focuses on the investigation of detecting soil profiles encountered during
exploratory drilling using continuous drilling parameters recorded in real-time, known as …

This study compared the results of European Union (EN) and American (ASTM) standards,
which are used to determine the abrasion resistance of rocks subjected to foot traffic. The …

Rock coring is an essential method of geotechnical site characterization for foundations
supported by rock, in which three possible phases of operation exist: inefficient, optimized …

Measuring while drilling (MWD) is the application of monitoring and recording drilling data
during the drilling process. Recent geotechnical MWD efforts have shown that specific …

Under certain ground conditions, obtaining adequate core specimens for logging can be
challenging, leading to low recoveries and poor rock quality designation (RQD). Borehole …

Drilling and blasting procedures are a critical part of mine planning activities and
improvements in this stage can lead to better productivity downstream and lower costs. One …

The focus of this paper is the assessment of load and resistance factor design (LRFD)
resistance factors (ϕ) for auger cast-in-place (ACIP) piles constructed in South Florida …
