CORRELATION BETWEEN UNIAXIAL COMPRESSIVE , good correlation between UCS and Is (50) Variation on test data has been observed This is expected for natural material like rock The insignificance relationship of strength signifies that there is possibility of insufficient data of rock sampl Although there are some trends that correlate UCS and Is 50 ,
Correlation between the point load index (Is(50)) and the , A good correlation between the unconfined compression strength test (UCS) and the point load strength (PLS) can be very useful because it allows for faster and cheaper testing than others with the same security to calculate the structures and performances of solid rocks A preliminary step to implement the correlation is to have a good method

Prediction of the uniaxial compressive strength and , It is commonly used in practice due to the ease of testing, simplicity of specimen preparation and possible field application ISRM [5] suggested that the ratio between uniaxial compressive strength (UCS) and point load index (Is(50)) varies between 20 and 25, although researchers have found various ratio which is depend on rock typ
Psychology Exam 3 Flashcards | Quizlet In classical conditioning, the ability to distinguish between a CS and other stimuli that do not signal a UCS In operant conditioning, responding differently to stimuli that signal a behavior will be reinforced or will not be reinforced
Computing in-situ strength of rock masses based upon RQD , Substituting the relationship between the RQD and modified joint factor with that between modulus ratio and strength ratio, the model shows successfully that using damage inclusive plastic parameter and RQD provides a relationship for estimating the strength of rock mass , Table 5, where UCS is the unconfined compressive strength Table 4 .
Correlation between Young's Modulus and Uniaxial , The relationships between Young's modulus and uniaxial compressive strength of rocks from the Haute Garonne, France, were investigated The relationships between these properties are described by simple regression analyz The results indicate an excellent correlation obtained between the modulus of elasticity and uniaxial compressive strength
Determine Unconfined Compressive Strength of Cohesive Soil The unconfined compressive strength (q u) is the load per unit area at which the cylindrical specimen of a cohesive soil falls in compression q u = P/A Where P= axial load at failure, A= corrected area = , where is the initial area of the specimen, = axial strain = change in length/original length .
psych X2 Flashcards | Quizlet Start studying psych X2 Learn vocabulary, terms, and more with flashcards, games, and other study tools , today learning theorists believe that of the relationship between the CS and the UCS is probably more important than timeing or frequency , which of the following statements best describes the relationship between UCR and CR
The four different temporal relationships between CS and UCS Trace conditioning takes place in a situation which is quite similar to delayed conditioning, but it is different from delayed conditioning due to the fact that the CS ceases before the UCS starts Thus, there is no physical overlap between the CS and UCS Here, the UCS is associated with the memory of the CS , Solution Summary
Correlation between Uniaxial Compressive Strength and , correlations between the UCS test results and the corresponding test results of Is(50) The data was analyzed statistically to determine the degree of correlation and the variability of results 2 Previous Investigations The point load test has been reported as an indirect measure of the compressive or tensile strength of the rock
USING THE POINT LOAD TEST TO DETERMINE THE UNIAXIAL , relationship between UCS and the point load strength could be expressed as: UCS = (K) Is50 = 24 Is50 (2) Where K is the "conversion factor" Subsequent studies found that K=24 was not as universal as had been hoped, and that instead there appeared to be a broad range of conversion factors Table 1 summarizes published results obtained for .
CBR and qu relationship - Soil testing engineering - Eng-Tips CBR value is also soil-dependant; ie two soils of different types with the same UCS will have different CBRs IF a particular correlation is valid, its validity will be limited to either in-situ or laboratory and also to CBR results obtained with particular surcharges (or none) AND to certain soil typ
Comparison of UCS to Bond Work Indices C and UCS values separated by the major rock types from a single African mine The three rock types do show a mild correlation between crushing Work Index and UCS (R² values between 01 and 04) Unfortunately, the correlation observed does not make sense: the correlation is expected to be positive
Correlation between the uniaxial compressive strength and , It is generally proposed that the relationship between the Is50 and the UCS value depends on the rock types and, also on the testing conditions This study investigates the correlation between the UCS and the Is50 of the Pungchon limestone, with a total of 48 core ,
Relationship between Su, qu anc c - Soil testing , Jun 05, 2004· What is the relationship between he undrained shear strengh(Su) and the unconfined compressive strength(qu) of a soft clay? AASHTO gives simplified pressure distributions with values based on the undrained shear strength for cohesive soils My boring data gives 07 tsf for qu and SPT N values ranging fom 2-4
(PDF) Correlation between the point load index, is(50 , Correlation between the point load index, is(50), and the resistance to unconfined compression in limestone from the comunidad valenciana, Spain
The Correlation of Unconfined Compressive Strength With , The IS50 to UCS correlation is reasonably accurate for crystalline or isotropic rocks but with weak sedimentary rocks, there is the potential for failure to occur along natural planes of weakness This creates significant scatter in data and questionable accuracy
Conversion of Point Load Test Results to Conventional , This paper aims to validity of the test methods were investigated represent an analysis of the data used to As the conclusion, the conversion factors are correlate the point load test index (Is50) with the presented and the point load test had been conventional strength tests such as UCS and determined as the most preferable indirect test ITS .

relation between uniaxial compressive strength, point load , Although linear-fit curve was not an ideal one but it provided better prediction of UCS for lower values of Is(50) Figure 5 - Relationship between UCS and Is50 based on power function The relationship was not applicable for smaller values of Vp as the equation had a negative intercept of – 1413 The range of Vp for prediction of UCS may be 7 .
Point load strength index of granitic irregular lumps , The correlation between the UCS and PLSI Is(50) of irregular lumps is found to be 2227, which is very close to the values of 2161 and 2172 for diametral and axial PL tests using the size correction factor of F = (De/50) 045 This indicates that the correlation between UCS and PLSI from point load tests on irregular lumps established in this .
