“…Also, the reduction of bearing capacity has been observed due to the increase in the burial depth of geotextile layers. Furthermore, the investigations indicated that the failure wedge of shell foundations in reinforced backfill conditions is formed deeper than that of conventional flat ones [17,18].…”

From a financial point of view, urbanization frequently enforces the clients to construct superstructures near the slopes, giving rise to increasing the risk of building instability. By conducting a series of small-scale plate load tests, this work aims to investigate the effects of installing geotextile reinforcement layers in sandy slope and reducing the apex angle of triangular shell strip footings. The results show considerable effect of using geotextile-reinforced layers and decreasing the apex angle on the ultimate bearing capacity of shell foundations. With increasing foundation distance from the slope, the adverse effect of the slope is reduced. However, as the distance decreases, the effect of reinforcement and apex angle is increased. For practical applications, empirical equations are also presented for determining the ultimate bearing capacity of the footings and scale effect as well. Finally, 3D numerical simulations are executed and compared with the experimental results.

“…With the rapid development of China's infrastructure, more and more transmission lines are being built in mountainous and high mountain areas, where the tower foundation plays an important role in the construction of transmission lines due to limited construction space and large-scale construction equipment, such as the anchor foundation [1], conical shell foundations [2]. The digging hold foundations are quite popular for special geological conditions and harsh construction environments due to their high bearing capacity and easy construction, which has been widely applied in mountainous and high mountain areas.…”

The physical model test is an effective method to study the bearing behavior of digging hold foundations due to its low cost and clear boundary conditions. Here, similar materials of rocks were configured and employed to study the bearing capacity and failure model of digging hold foundations in rock ground. Firstly, sixteen groups of material proportion schemes were employed to make similar materials of rocks, and the effects of four mix parameters were analyzed. Then, similar materials of rocks were employed to perform the uplift tests of digging hold foundations. The results show that the mass ratio of fine particles and aggregate has the greatest influence on the density and internal friction angle, while the cement moisture content has the greatest influence on the cohesion and compressive strength of similar materials of rocks. During the pull-out process of the digging hold foundation, the radial cracks radiate outward from the circumferential cracks, which is different from those in the field test because the ground is small and uniform without fissures inside. The foundation drives the surrounding similar materials to be pulled up as a whole with a certain failure angle, which increases from 35.7° to 42.5° as the internal friction angle decreases from 56° to 41°. In addition, the ratio between the equivalent shear strength in Chinese Code and uniaxial compressive strength falls in the range of 0.027–0.05.

The most used material in construction is concrete. This study aimed to investigate the impact of recycled aggregate on compressive and tensile strength in concrete. To address the issue of accumulating tons of recycled aggregates, a new method was developed using chemical additive fractions to convert these aggregates into valuable products. The overconsumption of materials is a significant problem that leads to route overflow, pollution, and road fragmentation. The mechanical properties of corroded concrete pipes were also examined through a series of tests and the development of an ABAQUS-based 3D finite element model. It was discovered that the inside of the pipe wall was more vulnerable to damage than the outside, with corroded areas experiencing large stresses and strains. As corrosion depth increased, so did maximum principal stress and hoop strain in the affected region. Fear increased rapidly at first (0-10°), then decreased rapidly (10-45°), before gradually decreasing with increasing erosion latitude (45-180°). Additionally, both circumferential strain and maximum principal stress increased rapidly with greater depth of coverage or increasing moving loads.
