Abstract

Dönüşüm faktörü (k) nokta yükü dayanım indeksi (PLI) ile tek eksenli basınç dayanımı (UCS) arasındaki oran olup kayaçların UCS tahmininde 60 senedir kullanılmaktadır. Birçok araştırmacı magmatik, metamorfik ve tortul gibi farklı jeolojik kökenlerdeki kayaçlar için UCS ve PLI arasındaki ilişkiyi araştırmıştır. Bazı çalışmalarda ise magmatik (piroklastik, volkanik, plütonik), tortul (kimyasal ve kırıntılı) ve metamorfik kayaçların (foliasyonlu ve foliasyonsuz) alt kökenlerine ilişkin k katsayıları araştırılmıştır. Literatür taramasına göre k katsayısı şeyl, kumtaşı ve kireçtaşı gibi bazı kayaçlar için yeterince çalışılmış olsa da bazaltlarda sınırlı sayıda çalışılmıştır. Bu çalışmanın amacı k katsayısının bazaltlar için değişimini bölgesel ve global açıdan incelemektir. k değerleri sıfır kesişim basit regresyon analizi ve UCS/PLI oranından elde edilmiştir. Bu çalışmada, bazaltlar için en uygun k oranı aralığının 17≤ k ≤ 20 olması gerektiği tavsiye edilmiştir. Tek bir değer vermek gerekirse, ANOVA sonuçlarına göre k değerinin 19 olması uygun olacaktır.

Prediction of the uniaxial compressive strength of basalts from the point load strength index using the conversion factor

Abstract

Conversion factor (k), the ratio between point load strength index (PLI) and uniaxial compressive strength (UCS), has been used for 60 years in UCS estimation of rocks. Many researchers have investigated the relationship between UCS and PLI for various rock types of different geological origins, such as igneous, sedimentary, and metamorphic rocks. The k values for subclasses of igneous (pyroclastic, volcanic, and plutonic), sedimentary (chemical and clastic), and metamorphic (foliated and nonfoliated) rocks were investigated in some studies. According to the literature review, although the k has been studied sufficiently for some rocks such as shale, sandstone and limestone, it has been studied in a limited number of basalts. The aim of this study is to examine the variation of k for basalts from a regional and global perspective. The k values were obtained by zero-intercept simple regression analysis and the UCS/PLI ratio. In this study, it is suggested that the optimal k ratio should be in the range of 17≤ k ≤ 20 for the basalts. To give a single value, it would be appropriate for k to be 19 according to the ANOVA results.
