Professor Dave Petley, of the University of Sheffield, said the mountain slope above the Bureya had a "pre-existing tension crack or depression" at an altitude of around 1,900 ft.
A growing tension crack on a ridge in Yakima County, Washington State, has propelled a number of residents living below it to evacuate their homes fearing a landslide.
It was made having an inverted layout (Figure 7) to properly place the air-coupled transducers upright along the midspan of the beam where tension crack occurred.
Hoek and Bray [11] presented an analytical solution for the plane failure mode in rock slopes, in which the upper slope surface and tension crack were assumed to be horizontal and vertical, respectively.
When the saturated expansive soil loses water, the soil moisture content decreases gradually and the matrix suction increases, and thus the soil becomes non-saturated and the elementary tension crack appears.

Since [[rho].sub.stbl] is expressed by the minimum reinforcement ratio required to maintain constant strain at the crack, the corresponding limit value for the shear strength capacity of the diagonal tension crack of slender beams can also be interpreted as [[rho].sub.stbl] equal to [rho] (in Eq (8)).
