Physical Model Tests of Expansive Soil Slope

Expansion Model Test of Expansive Soil in Different Stress State

“…Then the Handan strong-expansive soil was also analyzed. The conclusion is in accordance with this paper and relevant results can be found in [33].…”

Hydro-mechanical coupling effect on surficial layer stability of unsaturated expansive soil slopes

“…In other words, the rainfall infiltration will lead to a reduction in the FS only by decreasing the third term on the right hand side of Eq. (15). This scenario can be induced by either a decrease in the suction (negative PWP) for unsaturated condition or an increase in PWP for saturated conditions.…”

“…The value of PWP that brings the slope to failure (FS = 1) at a particular depth are also determined using Eq. (15) and illustrated in Fig. 20.…”

“…This is because the surficial soils essentially experience substantial swelling during the rainfall period [44]. Cheng et al [15] from the centrifugal modeling results suggested the instability of expansive soils can be attributed to the influence of swelling or heave within the slope surficial layer.…”

Study of evolution law of cracking for swelling mudstone of Sichuan central Redbeds in hydration process

“…On the one hand, the fracture cuts the rock and soil into a block shape, which destroys the integrity of the rock and soil body; On the other hand, it also provides an infiltration channel for rainwater or other water sources, further causing swelling-shrinkage deformation and expansion of the fracture of the expansive rock or soil. At present, the influence of fracture on the engineering properties and engineering problems of expansive geotechnical engineering has attracted the attention of relevant scholars [3][4][5][6]. At the same time, there are also many cracking test results of rock and soil.…”
