Dynamic compressive strength of rock salts ScienceDirect
2019年1月1日 They found that the compressive strength of the salt increased with increasing strain rate under confinement, and decreased with increasing temperature.
Dynamic compressive properties of Kalgoorlie basalt rock
2020年11月1日 For basalt rocks, Malik et al.12 investigated Deccan basalt rock and found the dynamic compressive strength between about 170 MPa and 260 MPa at a strain rate
New Confined Comopressive Strength Calculation
2019年11月13日 where: UCS = rock unconfined compressive strength DP = differential pressure (or confining stress) FA = rock internal angle of friction The adaptation of this
Unconfined Compressive and Splitting Tensile Strength of
The test results show that both the unconfined compressive strength (UCS) and splitting tensile strength (STS) at a given basalt fiber content increase significantly with increasing
Prediction of unconfined compressive strength and
2020年9月1日 The unconfined compressive strength (note: qu or UCS are used interchangeably in the literature, see Goodman 1980, 1 Hoek and Diederichs 2006, 2 Jaeger et al. 2007, 3 Labuz et al. 2018 4) and the deformation modulus ( E) of weak rock are, respectively, required for the calculation of the bearing capacity (Rowe and Armitage
Relationship between rock uniaxial compressive strength
2021年1月3日 The rock uniaxial compressive strength (UCS) is an indispensable parameter in rock mass stability analysis, underground chamber excavation, and support design for transportation, mines, and hydraulic projects. Accurate acquisition of the UCS is a precondition for engineering construction.
Quantification of statistical uncertainties of unconfined
2022年3月4日 Quantification of statistical uncertainties of unconfined compressive strength of rock using Bayesian learning method. Liang Han b School of Civil Engineering, Subsequently, Bayesian method was applied to quantitatively evaluate the uncertainties of statistical characteristics including the mean, variance, and scale of fluctuation (SOF) of
Rock Strength Prediction in Real-Time While Drilling
2021年5月3日 Abstract. The rock unconfined compressive strength (UCS) is one of the key parameters for geomechanical and reservoir modeling in the petroleum industry. Obtaining the UCS by conventional methods such as experimental work or empirical correlation from logging data are time consuming and highly cost. To overcome these drawbacks, this
Study on Mechanical Properties and Microstructure of
2023年3月1日 The effects of basalt fiber incorporation on the mechanical properties of red clay soils were investigated. Through the direct shear test, unconfined compressive strength test, and microstructure test, the shear strength curves and stress–strain curves of basalt fiber-modified red clay soils were obtained under different basalt fiber
FOHG Unconfined Compressive Strength of
4.3.2 Aggregate Crushing Value This Part of BS 812 describes a method for the determination of the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. All details and samples weights and results of ACV percentage is shown in table 9. Table 8.

An intelligent approach to predict unconfined compressive
2012年10月17日 Unconfined compressive strength (UCS) of rocks is one of the most important parameters in rock engineering, engineering geology, and mining projects. In the laboratory determination of UCS, high-quality samples are necessary; in which preparing of core samples has several limits, as it is difficult, expensive, and time-consuming. For this,
Confined compressive strength model of rock for drilling
2015年3月1日 The uniaxial compressive strength (UCS) has been used widely for drilling optimization and ROP prediction for a long time before some drill-bit experts realized that the use of UCS is somewhat problematic because the apparent strength of the rock in the downhole is apparently different from Ref. UCS [6], [11], [12], [13].
