Continuum model for the mechanical behaviour of an oriented fractured rock mass (In French) : Hadjhassen, F; Fine, J; Tincelin, E Proc 7th ISRM International Congress on Rock Mechanics, Aachen, 16–20 September 1991V1, P251–256. Publ Rotterdam: A A Balkema, 1991Show moreShow less...
A laboratory program, comprising a number of tests of scaled models of the pile/rock mass system has been conducted. A synthetic rock, known as Johnstone was used to simulate a naturally weathered and fractured siltstone. The load-deflection behaviour of the test piles was measured, and strain...
The model consists of a three-compartment energy balance integrated with a mechanistic psychological model inspired by the Theory of Planned Behaviour. This describes how important variables in a behavioural intervention can influence healthy eating habits and increased physical activity over time. The ...
The thermal behaviour measurements were recorded on even days between the 12th and 22nd of August 2018, for 6 days altogether. The selected body temperatures were obtained with a non-contact infrared thermometer (Fluke® 568 Infrared Thermometer) every 30 min from 8:00 am to 6:30 pm. We h...
Present constitutive models for rock fracture behaviour require information concerning the fracture geometry, on which the mechanical and hydraulic properties of the rock mass are greatly dependent. In this paper, measurements of rock fracture surfaces and aperture using a 3-D-laser-scanning technique ...
This phenomenon is substantially different from the bond behaviour of internal reinforcement, for which a bond length can always be designed for its full tensile strength if there is an adequate concrete cover. Many theoretical models have been developed to predict the bond strength of FRP-to-...
6,7. The leaching effect of acid rain on calcareous sandy loam was simulated in which acid rain with different pH aggravated the loss of phosphorus in the soil8,9. Huang et al.10found that high temperature and acid chemical solution could affect the mechanical characteristics of rock mass ...
