ELEKTRİK ÖZDİRENÇ YÖNTEMİYLE PİROKLASTİK KAYAÇLARIN İNDEKS-DAYANIM ÖZELLİKLERİNİN BELİRLENMESİ

Öz

Bu çalışmanın amacı, çalışmaya hız kazandıran ve çalışma maliyetini azaltan elektrik özdirenç yöntemiyle piroklastik kayaçların indeks ve dayanım değerlerini belirlemektir. Bu amaçla 12 farklı piroklastik kayaç örneğinin indeks-dayanım ve elektrik özdirenç değerleri laboratuarda ölçülmüştür. Kayaçların elektrik özdirenç değerleri ile uyumlu indeks-mekanik özellikleri arasında basit regresyon analizi yapılmıştır. Kayaçların elektrik özdirenç değerleri ile indeks-dayanım özellikleri arasında güçlü belirleme katsayıları bulunmuştur. Elde edilen bu ilişkilere göre, elektrik özdirenç yönteminin, düzgün şekilli numune alımının güç veya olanaksız olduğu kayalarda ve/veya tarihi yapılarda kayaçların mühendislik özelliklerinin tahmininde tahribatsız bir yöntem olarak kullanılabilirliği ortaya konulmuştur.

DETERMINATION OF INDEX-STRENGTH PROPERTIES OF PYROCLASTIC ROCKS BY ELECTRICAL RESISTIVITY METHOD

Abstract

The aim of this study is to determine index and mechanical properties of pyroclastic rocks by means of the relatively fast and cost-effective electrical resistivity method. For this purpose, index-mechanical and electrical resistivity values of 12 different pyroclastic rocks were determined in the laboratory. Simple regression analyses were made between index-mechanical properties of the rock samples compatible with electrical resistivity values. Strong relationships were found between index-mechanical properties and electrical resistivity values. Based on these relationships, the electrical resistivity method can be used to assess index and mechanical properties of rocks as a non-destructive method where collecting regular shaped rock samples are difficult and impossible.

Keywords

• Electrical resistivity,index-mechanical properties,pyroclastic rocks,simple regression analysis
