“…Plaxis 2D has advanced constitutive models for the simulation of the nonlinear, time-dependent, and anisotropic behavior of soils. Such higher-order elements as quadratic 6-node and 4th-order 15-node triangular element are suitable to model the deformations and stresses in the soils (Wu et al, 2014). Plaxis 2D uses Biot consolidation theory, and the formulae are described in Eqs 1, 2 (Wang and Zheng, 2010;Sun et al, 2015).…”

Dumping is the main disposal method of the excavated soil from underground engineering in China; however, due to a lack of construction experiences and technical standards, landslide disasters often occurred during rapid dumping of excavated soil in soft soil regions. In this paper, geotechnical tests were conducted on the excavated soil from a foundation engineering site in Hangzhou, where the excavated soil would be used to construct a piled mountain. On this basis, a numerical study was carried out to investigate the effects of the design parameters (heap height, slope gradient) and construction parameters (layer thickness, heap speed) on the dump stability and failure mode. The results show that the safety factor of the excavated soil dump decreases with increasing heap height, slope gradient, layer thickness, and heap speed. The potential slide surfaces are toe circle, and compared to layer thickness and heap speed, the heap height and slope gradient have more remarkable influence on the depth and area of potential slide mass. The heap height limit increases with a decrease in slope gradient, and the heap speed limit decreases with an increase in layer thickness. Under the premise of ensuring the slope stability, the optimal design and construction parameters were obtained, i.e., heap height 28 m, slope gradient 1:2.75, layer thickness 1.0 m, and heap speed 0.50 m/day. Compared to the original design scheme, the storage capacity increases by 20.01%, and the construction duration decreases by 30.25% in the optimal design.

“…Stability of a high loess slope reinforced by the combination system of soil nails and stabilization piles was analyzed by reference [35] and they summarized that by using only one support measure of the soil nails and stabilization piles cannot meet the requirements of the overall stability of the slope. When the depth of excavation is relatively shallow, the contribution to the overall stability of soil nails is larger than piles; and with the increment of the excavation depth, the effect of stabilization piles began to dominate.…”

The slope stability was researched over the past decades, understandings the behavior of nailed soil slopes, with their properties and characteristics, have guided to development of enhanced recognizing of the variation in nailed soil slopes parameters. Failures can arise over time, hence the identification of the necessities and the restrictions of laboratory and in situ testing for evaluating nailing parameter have to be deeply understood. Many researcher have enriched and refined the knowledges of the principles of soil nailing mechanics that associate soil behavior to slope stability and factor of safety. This paper is aimed to explore some of important state of the art development of nailed soil slope and analytical techniques extended by extensive investigation of the mechanics of slope stability analyses. The most significant effective parameter that play important role in slope safety factor in almost of many works are length, nailing angle, and distance between center to center of nails. Slope angle, connection of nailed head, the distance with toe and nail diameter were also the points that cannot be neglected in their study. Choosing the proper cable or pile element in the finite element modeling and the mobilized both axial and shear forces are also reviewed in this paper.
