Estimating uniaxial compressive strength of rocks using genetic .

The aim of this paper is to estimate the uniaxial compressive strength (UCS) of rocks with different characteristics by using genetic expression programming (GEP). For this purpose, five different types of rocks including basalt and ignimbrite (black, yellow, gray, brown) were prepared. Values of unit weight, water absorption.

Rocks are rated on the on the Moh's Hardness Scale which rates the rocks on the scale from 1 to 10. Rocks with hardness 1-3 are soft rocks from 3-6 are medium hardness rocks and 6-10 are hard rocks. The hardness of Basalt is 6 whereas its compressive strength is 37.40 N/mm2. Streak is the color of rock when it is.
