Is Global Warming Hampering the Stability of Substructure?
In the present environmental situation, the temperature of earth’s atmosphere as well as the earth’s sub-surficial temperature is increasing at a very tremendous rate. Since 1979, global average land temperatures have increased about twice as fast as global average ocean temperatures (0.25 ℃ per decade against 0.13 ℃ per decade). Though the figure seems to be insignificant when considered on a global average, it sounds to be significant when particular regions on earth are considered. This increase in temperature is not only affecting the habitation of living species but also the habitation and stability of structures by affecting their foundations. Hence efforts have been made in this study to interpret and plot the effects of global warming on substructures by provision of mathematical and theoretical proofs. In the study, the phenomena of thermal expansions and thermal contractions of material subjected to temperature variations have been exploited, to attain at the result. This depicts a significant impact of temperature stress on the stability of subsurface structures which are in contact with subsurface geological structures. The principal upon which the study is based is thermal: Different materials expand or contract thermally when subjected to temperature variations; the same material expands or contracts thermally to a different extent at various degree of temperature variations. The study deals with mathematical expressions to plot the effects of global warming on stability of substructures.
