The experiments aim at analyzing the associated mesoscale-macroscale phenomena in the fracture process of the specimens. Hence, a fast, non-destructive method for assessing the strength of a rock mass after a fire would be useful in... Failures of the surrounding rock mass have been identified as the most serious threat to the stability of underground water-sealed petroleum storage depots. Brazilian tensile strength (BTS) tests were conducted by another researcher under the supervision of the second author at NTU. The latter is achieved by considering the geomet-rical relationship between the joint orientation and the scanline/rock core orientation. As such, it is of high practical value to correctly evaluate the rock brittleness. However, the microcracking mechanisms of thermally-treated granite under mode I loading are very complex.

Quickly and easily compare or convert St. Louis time to Hong Kong time, or the other way around, with the help of this time converter. In the present study, special attention... Tunnels and caverns excavated for the purpose of mining tend to be designed for short term use and would usually be unlined. Louisa Wong. This paper presents an experiment... En-echelon fractures have been commonly observed in a fault zone. In order to better understand the mechanical properties of graded crushed rocks (GCRs) and to optimize the relevant design, a numerical test method based on the particle flow modeling technique PFC2D is developed for the California bearing ratio (CBR) test on GCRs. Brazilian disc tests, with the aid of a high speed video system to monitor and record the cracking processes, are conducted on dry and wet specimens.

Louis has 1 job listed on their profile. In practice, the peak shear strength of rock joints is not dictated only by the surface roughness, but also the degree of matching between the joint surfaces. The closure behavior of rock joints remains a problem of interest with applications in many practical engineering problems.
