CORRELATIONS OF POINT LOAD INDEX AND PULSE VELOCITY WITH THE UNIAXIAL COMPRESSIVE STRENGTH FOR ROCKS

Journal of Engineering, 2011
Rock engineers widely use the uniaxial compressive strength (UCS) of rocks in designing surface and underground structures. The procedure for measuring this rock strength has been standardized by both the International Society for Rock Mechanics (ISRM ...

Predicting grout’s uniaxial compressive strength (UCS) for fully grouted rock bolting system by applying ensemble machine learning techniques [PDF]

Neural Computing and Applications
AbstractThis study proposes a novel system for accurately predicting grout’s uniaxial compressive strength (UCS) in fully grouted rock bolting systems. To achieve this, a database comprising 73 UCS values with varying water-to-grout (W/G) ratios ranging from 22 to 42%, curing times from 1 to 28 days, the admixture of fly ash contents ranging from 0 to ...

The Uniaxial Compressive Strength of Soft Rock

Civil Engineering Dimension, 2007
Soft rock is a term that usually refers to a rock material with a uniaxial compressive strength (UCS) less than 20 MPa. This low strength range might be influenced by physical characteristics, such as size, saturation, weathering and mineral content.

EVALUASI FAKTOR KEAMANAN LERENG BERDASARKAN NILAI GEOLOGICAL STRENGTH INDEX (GSI) DAN UNIAXIAL COMPRESSIVE STRENGTH (UCS) DALAM PERENCANAAN LERENG

Jurnal Kacapuri : Jurnal Keilmuan Teknik Sipil, 2023
Suatu konstruksi yang memerlukan pekerjaan galian tanah (batuan) membutuhkan perencanaan yang baik karena sisi-sisi galian akan terbentuk lereng. Faktor Keamanan (FK) suatu lereng dipengaruhi oleh beberapa faktor, salah satunya adalah nilai Geological Strength Index (GSI) dan Uniaxial Compressive Strength (UCS).
