Abstract

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
