“…However, through the shear tests on five layers of soilbags arranged in a staggered manner under different vertical loads, Fan et al (2019) found that the sliding surface in the shear tests was nearly horizontal under small vertical loads,and ladder-like under large vertical loads, as shown in Fig. 9.…”

“…Therefore, in case of large vertical loads, the shear strength should not be calculated using Equation ( 4) because the sliding surface changed. Instead, the methods proposed by Fan et al (2019) should be used. The shear stresses in the middle, stable part (AC) and the final, stable part (DB) in T1P are called the intermediate shear stress, τint, and final shear stress, τf, respectively.…”

“…However, the only interlayer sliding failure mode, a horizontal line on the plane, is considered when stacked soilbags are subjected to shear forces, and interlayer frictional resistance between vertically stacked soilbags is treated as their shear strength. However, Fan et al (2019) found that the sliding surface in a model-retaining wall stacked in a staggered manner is ladder-like due to the insertion of soilbags. The soilbag is a composite of woven bags and the materials filling them.…”

The Shear characteristics of stacked soilbags are related to their interlayer arrangements and properties of the materials with which the bags(geosynthetics) are filled. To study the effects of those factors on the shear strength and failure mode of stacked soilbags, a series of shear tests were conducted. The results show that although the shear failure surface occurred at the horizontal interface between soilbags when they were arranged vertically, it was ladder-like when the soilbags were arranged in a staggered manner. The angle of insertion was found to govern the shape of the shear failure surface, and, thus, the final shear strength of soilbags arranged in a staggered manner. Two shear failure modes of the stacked soilbags were observed with different infilled materials. When the frictional resistance of the contact interface was smaller than the shear strength of the materials with which the bags had been filled, only interlayer sliding failure occurred. Otherwise, the simple shear failure of materials filling the bags occurred first, followed by interlayer sliding failure.

The No. 4 clay core rockfill dam of the Gongming Reservoir experienced leakages when the reservoir water level was low. To analyze the leakage causes, a series of seepage tests were conducted on the dam materials in this paper. And a three-dimensional finite element stress-seepage coupled calculation model of the dam was established to study the deformation and stresses of the dam under the condition of normal storage water level and the sharp drop in the storage level. The test results show that the permeability coefficient of the clay core material is close to that of the dam shell material, resulting in the leakage of the dam under the condition of the low-water level. The simulation results show that the dam deforms a little under the condition of normal storage water level and the sharp drop in the storage level, and the stress distribution under the condition of the sharp drop in the storage level is basically consistent with that under the condition of normal storage water level. The safety factors of the dam under the two conditions meet the requirements of the specification, but the margin of the safety factor is small.

Mesoscopic Failure Behavior of Strip Footing on Geosynthetic-Reinforced Granular Soil Foundations Using PIV Technology

Two-dimensional model tests combined with PIV technology were conducted to study the failure behavior of strip footing on geosynthetic-reinforced granular soil foundations on a mesoscale. The results showed that geosynthetic reinforcements improve the bearing capacity of granular soil foundations; however, the effectiveness of the reinforcement was affected by the position, length, and number of geosynthetics. The mesoscale factor affecting the reinforcement effectiveness was the size of the sliding wedge in the foundation, which was changed by the embedded geosynthetics. As the depth, length, number, and vertical spacing of the reinforcements varied, three possible failure modes occurred in the reinforced foundations: failure above the top reinforcement layer, failure between reinforcement layers, and failure similar to footings on the unreinforced foundation.
