satisfactory correlations Based on the results, new strong correlation with correlation coeffecients above (R2 [080) are introduced for predicting the UCS, Is(50), U and RN and reasonable good correlations (R2 C 078) are introduced to predict TS and DUW from P-wave velocity of different intact rock core sampl There is a discrepancy between..

An understanding of rock strength is important for designing recovery plans for a reservoir and for developing an appropriate reservoir simulationA detailed discussion of rock failure can be found in Rock failure relationships and Compressive strength of rocksBut the data needed for these methods may not be readily available, so there is a desire to use data available from well logs that are ...
Using standard laboratory tests to determine UCS is a difficult, expensive and time-consuming task The main purpose of this study is to develop a general model for predicting UCS of limestone samples and to investigate the relationships among UCS, Schmidt hammer rebound and P-wave velocity (V P)..
fr En utilisant des comparaisons graphiques et mathématiques entre les valeurs UCS et ls, un facteur de conversion de 16 est obtenu pour avoir la valeur UCS à partir de la valeur ls en In this paper the unconfined compressive strength (UCS), the tangent and secant Young's modulus of 35 British sandstones are analysed statistically..
Rock units with at least 3 UCS and 3 PLT results were selected for inclusion in the data base The mean UCS, mean Is50, the standard deviations, and the CI95 were calculated for each rock unit Many of the studies summarized in Table 1 compared a suite of point load tests to a single UCS test..
Bearing Capacity of Rocks Intact Rock MassIntact Rock Mass A rock mass with joint spacing greater than 4 to 5 times the width of the footing Local and General shear failure is associated to brittleGeneral shear failure is associated to brittle and ductile rock respectively..
