A New Method for Forecasting Uniaxial Compressive Strength of Weak Rocks
The uniaxial compressive strength of weak rocks (UCSWR) is among the essential parameters involved for the design of underground excavations, surface and underground mines, foundations in/on rock masses, and oil wells as an input factor of some analytical and empirical methods such as RMR and RMI. The direct standard approaches are difficult, expensive, and time-consuming, especially with highl...
متن کاملOn Weak Ground
Though the study of grounding is still in the early stages, Kit Fine, in ”The Pure Logic of Ground”, has made a seminal attempt at formalization. Formalization of this sort is supposed to bring clarity and precision to our theorizing, as it has to the study of other metaphysically important phenomena, like modality and vagueness. Unfortunately, as I will argue, Fine ties the formal treatment of...
متن کاملPropagation of Vibration from Rail Tunnels: Comparison Results for Two Ground Types
Detailed measurements of vibration transmission from an underground rail line in Sydney and a line in a deep cutting in Perth have recently been conducted. The propagation characteristics of these two ground types are very different, and neither fits comfortably with standard theoretical models of vibration transmission through a uniform ground. In Sydney, the results can generally be modelled ...
متن کاملAppraising Weak and Strong Sustainability: Searching for a Middle Ground
This paper seeks to address the issue of weak and strong sustainability as well as the search for a middle ground. It discusses the differences between weak and strong sustainability while arguing for the harmonisation of both nature and humankind. Achieving harmony requires a move towards an idealist eco-sociofeminist point of view. Through this, full equality and balance may be attained.
متن کاملMutualism supports biodiversity when the direct competition is weak
A key question of theoretical ecology is which properties of ecosystems favour their stability and help maintaining biodiversity. This question recently reconsidered mutualistic systems, generating intense controversy about the role of mutualistic interactions and their network architecture. Here we show analytically and verify with simulations that reducing the effective interspecific competit...
