intact rock strength by different means on the same rock masses. The results show that in many cases an estimation of intact rock strength by 'simple means' is more representative for establishing the intact rock strength of a rock mass than establishing the intact rock strength by more elaborate testing.

Apr 28, 2014· The diametral test is conducted on rock core sample. Minimum of 10 test specimens are required to find out the average value of point load strength index. This test can be conducted on the core specimens which are completely dry or after soaking it for 7 days. Measure the total length (l) and diameter (d) of the core specimen.

Aug 25, 2016· In this short presentation, we are going to examine the external resistance of a ground anchorage and, more specifically, the methods for estimating the bond strength (q u) between the grout and the surrounding rockmass inserted into the geotechnical design. The case of rock anchorages and related dependencies are also going to be discussed.

Therefore in situ testing is commonly used in granular soils. Typically, testing is carried out using either field geophysics, or penetration testing. When accurate values of compressibility are required, then plate testing may be used. 4. Weak, fissile or fractured rock. The strength and compressibility of fractured rock is
