Revisiting rock classification to estimate rock mass properties

evaluation of rock mass deformability

One of the most important effective parameters in design of engineering structures is deformability of rock mass. Benchmark of rock mass deformability is the deformation modulus that directly or indirectly obtained. Since the determination of rock mass deformation modulus indirect method by in-situ tests is time-consuming, costly and difficult from executive operations aspect, so it’s correctly...

A new approach for application of rock mass classification on rock slope stability assessment

The objective of this paper is to present a new rock mass classification system which can be appropriate for rock slope stability assessment. In this paper an evaluation model based on combining the Analytic Hierarchy Process (AHP) and the Fuzzy Delphi method (FDM)was presented for assessing slope rockmass quality estimates. This research treats the slope rockmass classification as a group deci...

Stress Measurement in Rock Mass

Understanding and estimating the rock stress state has become increasingly important as nowadays numerical models are mainly used as rock engineering design tool. The objective in determining rock stresses may, in many cases, be seen as an interactive process. The type of data needed may change, depending on at what stage an underground project is in. Further more, preliminary measurements may ...

Probabilistic Based Rock Texture Classification

The classification of natural images is an essential task in computer vision and pattern recognition applications. Rock images are the typical example of natural images, and their analysis is of major importance in rock industries and bedrock investigations. Rocks are mainly classified into three types. They are Igneous, Metamorphic and Sedimentary. They are further classified into Andesite, Ba...
