The evaluation of engineering rock mass quality is fundamental work for the engineering
activities of rock mass. The increasing scale of rock mass engineering necessitates higher …

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 …

The engineering behaviour of rock is strongly associated with the anisotropy, which exists at
different scales for construction safety and evaluation of rock properties. It is also well known …

The relationship between landslides and rock mass strength is fundamental for assessing
landslide hazards. Some researchers have proposed that there is an inverse relationship …

Rock quality designation (RQD) has been considered as a one-dimensional jointing degree
property since it should be determined by measuring the core lengths obtained from drilling …

Anisotropy is an inherent property of rocks. It refers to the different response of the rock
properties in each direction. Understanding the anisotropy characteristics of rock failure by …

Real-time and accurate prediction of surrounding rock grade is crucial for tunnel dynamic
construction and design. However, the internationally accepted semi-quantitative methods …

The stability of rock slopes with weak planes has been practically evaluated by the empirical
slope mass rating (SMR) and kinematic analysis. It is worth clarifying the rationality of the …

Transverse anisotropy plays an important role in the engineering behavior of rock masses.
This study examines the transverse anisotropic spatial variations and evaluates them using …

Concrete cracking is prone to occur in secondary linings during tunnel operation. In this
article, the Zhegu mountain tunnel, which is mainly situated in weak phyllite stratum, was …
