Several series of rockfall tests have been conducted in three different geological environments in New South Wales. The results of the tests show a large variability of the motion parameters, which is due to the natural variability of the blocks and to the randomness of the impact positions. Also, values of kn consistently and systematically higher than the benchmark values from the literature have been inferred. Despite there being no clear correlation between the restitution coefficients and the rotational energy, rotational phenomena are believed to be at the origin of such results.]]> Wed 11 Apr 2018 10:17:13 AEST ]]> A dimensionless model for soil swelling behaviour https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:6213 Wed 11 Apr 2018 09:36:32 AEST ]]> Sensitivity analysis of a new model to predict the survival probability of artificial rock blocks upon dynamic impact https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39451 Wed 08 Jun 2022 09:41:17 AEST ]]> Experimental testing of rockfall barriers designed for the low range of impact energy https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:13887 Tue 24 Aug 2021 14:24:46 AEST ]]> Statistical evaluation of rockfall energy ranges for different geological settings of New South Wales, Australia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:13888 Tue 24 Aug 2021 14:23:20 AEST ]]> A Large-Scale Application of the Stochastic Approach for Estimating the Shear Strength of Natural Rock Discontinuities https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50910 Tue 22 Aug 2023 11:24:51 AEST ]]> Comparison of imaging technologies for geotechnical investigation of abandoned coal mine workings: A case study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43100 Tue 13 Sep 2022 12:40:35 AEST ]]> Development of an apparatus to track rock fragment trajectory in 3D https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45909 Tue 08 Nov 2022 09:25:02 AEDT ]]> A rigorous multiscale random field approach to generate large scale rough rock surfaces https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45567 Tue 01 Nov 2022 14:46:59 AEDT ]]> Impact of grading on steady-state strength https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37164 Thu 26 Nov 2020 16:22:18 AEDT ]]> Mechanical behaviour of an Australian mudstone subjected to heating treatment at high-temperatures https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23045 Thu 18 Aug 2016 14:52:55 AEST ]]> Effect of sampling interval on the output statistics of large 3D discontinuity surfaces generated by a multiscale random field model https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40308 Thu 07 Jul 2022 16:49:38 AEST ]]> Problems in testing problematic expansive soils https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12180 Sat 24 Mar 2018 08:09:19 AEDT ]]> Compression-induced saturation in coal mine spoil piles https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:17865 r) at constant water content. In this study, a typical spoil derived from Permian-aged sandstones and mudrocks, is subjected to stresses up to 20 MPa, with the corresponding changes in degree of saturation and suction measured. The results show that loose spoil with a water content of around 12% (Sr=25%) will collapse to become saturated under a stress of 7 MPa. In contrast, loose spoil with a higher water content of around 16% will collapse to become saturated under a stress of only 1.5 MPa. From these results, a phenomenon is identified whereby spoil in the seepage and capillary zones at the base of very high spoil piles can collapse to a state of saturation. A discussion is provided on the consequences of this for the matric suction and unsaturated shear strength of these spoil materials, which constitute the foundation layer of the pile.]]> Sat 24 Mar 2018 08:03:29 AEDT ]]> Effect of coal addition on the swelling potential of a weathered claystone https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:20757 Sat 24 Mar 2018 08:00:25 AEDT ]]> The CPTU as a tool for interpreting depositional environments in estuarine deposits https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:6246 Sat 24 Mar 2018 07:48:39 AEDT ]]> Evaluation of short non-monotonous dissipation test data https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:6171 Sat 24 Mar 2018 07:44:38 AEDT ]]> Dissipation tests in saline environment https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29383 Sat 24 Mar 2018 07:36:16 AEDT ]]> Some comments on the CPTu and DMT dissipation tests https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29384 t50 is related to the inflexion point of the total stress-time curve.
