Rock engineering rating system for assessing the suitability of armourstone sources

Abstract

The process involved in assessing and selecting a potential source of armourstone of suitable quality is one of great complexity. The process involves the inspection and evaluation of the quarry and its production methods, testing of the processed stone, evaluation of the quality of both intact and processed stone, and consideration of both the transportation methods and placement techniques. The entire process, from quarry selection to placement at the project, may be viewed as a rock engineering system. The use of a rock engineering interaction matrix simplifies an understanding of how various factors affecting the quality of quarried armourstone are interrelated. Through this understanding of the various interrelationships a weighted rock engineering rating system may be developed for the assessment of the suitability of various armourstone sources. Such a rating system is designed to pull together all the factors related to both the field and laboratory investigations of a potential source, enabling geologists at all experience levels to arrive at a well-founded conclusion concerning the potential quality of stone produced from a particular armourstone source. at James Cook University on March 15, 2015 http://egsp.lyellcollection.org/ Downloaded from at James Cook University on March 15, 2015 http://egsp.lyellcollection.org/ Downloaded from Generation of seismic waves by explosions in prestressed media.

Dynamics of Coastal Systems Using GIS Analysis and Geomaterials Evaluation for Groins

“…As a result, the methodology developed provides a geotechnical characterization that is useful in the planning of maritime repair works. Moreover, this methodology gives further support to the importance of establishing the availability and the geotechnical quality and durability of geomaterials to be used at a particular site at the time of extraction from quarries when one is considering geoengineering design options (e.g., Lienhart, 1998;Latham et al, 2006a,b;and Manoliu and Radulescu, 2008). On the other hand, there is also a concern for evaluating the structural condition of protection work after the construction for monitoring and maintenance.…”

“…These visual evaluations were supported by the use of the inspection datasheet, where the most important aspects and parameters were registered, including lithology, weathering grade, petrophysical characteristics, and geomechanical features of block materials (Fookes and Poole, 1981;Lienhart, 1998). For the evaluation of the uniaxial compressive strength of rocks and materials (concrete) in the groin, the Schmidt Hammer technique was used (e.g., Katz et al, 2000;Kahraman, 2001).…”

“…Çalışma alanının GB-KD hattında enine kesiti. (CIRIA, CUR, CETMEF,2007 (Lienhart, 1998). Bu yöntemin uygulanmasında; jeolojik faktör, üretim faktörleri ve kayanın özellikleri en önemli ölçütlerdir.…”

“…Koruma yapısının kaya mühendisliği sınıflama sistemi yapılırken, farklı değişkenler için sebep-etki dereceleri ve bu derecelere ait indeks sayılar belirlenmektedir (Lienhart, 1998). Bu indeks sayılar kaya malzemesinin durumuna bağlı olarak Lienhart (1998) tarafından verilen şekilde kullanılmaktadır.…”

Weathering of Rock as Armourstone: A Case Study on Bahrain Limestone

“…The first work was proposed by Latham (1991), who presented a method for predicting armourstone mass loss in-service. Lienhart (1998) presented a method of evaluating the quality of armourstone sources. These researches were combined into two separate degradation models by Latham, Lienhart and Dupray in 2006 and these models were presented in the second edition of the CIRIA Rock Manual in 2007.…”
