Влияние температурных колебаний на склоновые перемещения одиночных обломков

Аннотация

At slopes with angle α which is less than the angle of repose β individual dry rock: fragments may move downslope due to diurnal changes of temperature. The value of as parallelepiped al fragment movement per day is: d=x∆tltg α ctg β, where x - is linear heat expansion coefficient, ∆t - range of the rock fragment temperature, l -the fragment's length (along the slope dip).
