PREDICTION OF UNCONFINED COMPRESSIVE STRENGTH OF ROCKS

Unconfined compressive strength UCS of rocks is a crucial parameter in designing geotechnical structures Owing to difficulties in obtaining proper samples for UCS test as well as the point that conducting UCS is relatively expensive the use of indirect methods for UCS estimation has drawn considerable attentions This review paper is aimed to briefly highlight different

What is Compressive Strength from

Compressive strength is a limit state of compressive stress that leads to failure in a material in the manner of ductile failure infinite theoretical yield or brittle failure rupture as the result of crack propagation or sliding along a weak plane

Title Estimating the unconfined compressive strength

Abstract Conventionally many researchers have used both regression and black box techniques to estimate the unconfined compressive strength UCS of different rocks The advantage of the regression approach is that it can be used to render a functional relationship between the predictive rock indices and its UCS
