The quantitative determination of the geological strength index (GSI) and disturbance factor
(D) in the Hoek–Brown failure criterion is of great value because it can increase the …

The geological strength index (GSI) is one of the most exceptional rock mass classification
system which is used to evaluate very weak and highly jointed rock mass by different …

This paper presents a machine learning (ML)-based method for predicting the end-bearing
capacity of rock-socketed shafts. For ML model training and testing, a database of 151 test …

Abstract Characterization of jointed rock masses and evaluation of their mechanical
properties are challenging tasks in rock engineering. This paper presents an experimental …

Field evaluation of the strength properties of jointed rock masses is a challenging task in
geotechnical engineering. Typically, laboratory tests using small jointed specimens have …

The Baihetan super-high arch dam is constructed under complicated geological conditions,
including large-scale columnar jointed basalt with closely spaced joints and multiple …

The Junchang tunnel is a part of a major project in the Censhui highway in Guangxi
province, China. The weathered granite part of the tunnel is approximately 180 m long with …

The engineering classification of rock masses is the basis of rock engineering design and
construction. We propose and apply a quick basic quality (BQ) classification method based …

Reliably assessing the quality and mechanical properties of rock masses is crucial in
underground engineering. However, existing methods have significant limitations in terms of …

The composite lining load of a deep-buried tunnel is one of the key problems in tunnel
support design. This study establishes four support cases to discuss the loads on primary …
