<p>In the construction of a tunnel, the characterization of the rock mass is performed in three different steps, in the pre-investigations, in the engineering geological forecast and in the tunnel mapping during construction. There has in previous work been ...

In this work Data Mining tools are used to develop new and innovative models for the estimation of the rock deformation modulus and the Rock Mass Rating (RMR). A database published by Chun et al. (2008) was used to develop these models. The parameters of ...

In this study, applicability of the excavatability classification systems in underground excavations is investigated. For this purpose, the entrance portal of the Konak&ouml;n&uuml; (Araklı-Trabzon) tunnel, excavated in volcanic rocks within the scope of Black ...

This paper aims to provide a correlation between the two quality indexes, with the intention of supplying a tool to aid in both the design phase and the daily control of work execution. The formulas were obtained from the on-site observation of rocky masses ...

The paper presents geological and engineering geological characteristics of the flysch in outlined area which is expected to have a lot of similarities with very well defined and investigated flysch deposits in Split.The investigated area belongs to the ...

<p>The focus of this study is on potential damages to buildings resulting from expansive soils in Tanzania, particularly clay soils in Kibaha. For the fact that most of the affected structures are founded on expansive soils, a clear understanding of the behaviour ...

After 35 years of use throughout the tunnelling world, the RMR and Qclassifications have proved themselves on numerous projects. They stillface misconceptions however, as reflected in recent articles in T&amp;TInternational. Here, Nick Barton, of Nick Barton ...

This paper questions the application of rock mass classification systems in engineering geology problems.

<p>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 ...

This paper presents the result of comparison between the modulus of deformation obtained from dilatometer tests and the geomechanical quality of the rock mass using the RMR classification and the basic intact rock properties such as uniaxial compressive strength ...
