“…The cost of the piled foundation was compared with the piled raft foundation, resulting in a cost reduction of 49.61% compared to the conventional design [97]. Another study focused on the life cycle cost analysis (LCC) of landslide stabilization piles [98]. Among the cited analyses, there is a predominant focus on piling techniques, with a few dealing with ground improvement solutions, such as [99].…”

This study aims to investigate researchers’ interest in the topic of integrated life cycle design in the context of geotechnical works (ground improvement and piling solutions). In the first part, the authors conducted a literature review to assess the popularity of sustainable development themes in research related to the aforementioned topics using the VOSviewer software. Several main categories were then identified, such as environmental aspects, noise, vibrations, economic aspects, process efficiency, and the most frequently addressed issues were highlighted for each category. The conclusions drawn from the review were used to conduct a decision-making trial and evaluation laboratory (DEMATEL) analysis to investigate the inter-relationships between the identified factors and their impact on the implementation of integrated design principles in the relevant technologies. Analysis carried out using the VOSviewer program revealed that publications on ground improvement and piling solutions mainly focus on two thematic areas: design and the broadly understood materials used in these methods. A more in-depth review confirms the scarcity of publications addressing the technology selection process from a multi-aspect perspective, particularly in terms of sustainable development criteria and the assessment/characterization of individual technologies. This highlights a significant research gap. This study notes the promising potential of new, green materials in sustainable geoengineering and the need for comprehensive tools to assess their sustainability. It also acknowledges the potential cost savings offered by sustainable technologies, while discussing the challenges in their adoption due to resistance to new technologies, the lack of consistent emissions data, and the absence of uniform standards. These factors contribute to difficulties in comparing and implementing sustainable solutions effectively.

“…Landslide is one of the most serious geological hazard in the world, causing a large amount of human and property loss every year. In engineering practice, there exist many technical measures to control the evolution of landslides (Ito and Matsui 1975;Poulos 1995;Low 2005;Low et al 2011;Wang et al 2013;Miao et al 2018;Yu et al 2019;Yao et al 2020), among which the stabilizing pile is the most commonly used measure due to its various advantages, including its large stabilizing force, small disturbance on original slopes, and reliable construction quality, among others (Ito and Matsui 1975;Hassiotis et al 1997;Cai and Ugai 2000;Won et al 2005). However, designing stabilizing piles is challenging because of the complicated interaction mechanism between soil and the stabilizing piles, which may determine the failure modes of the reinforced slope and the stabilizing pile.…”

Many uncertainties exist in pile-stabilized slopes which make their design substantially complicated. In this paper, a firstorder reliability method (FORM) based on a support vector machine (SVM) and uniform design (UD) is proposed to investigate the reliability of a pile-stabilized slope. A deterministic model considering soil-pile interaction and using a strength reduction method based on the displacement criterion is employed to calculate the factor of safety and the corresponding pile-bending moment. The uncertainties involved in both the soil and the stabilizing pile are taken into consideration in the proposed method. Two typical failure modes, namely the insufficient factor of safety of a pile-stabilized slope and the insufficient flexural bearing capacity of stabilizing piles, are investigated from a probabilistic viewpoint. The proposed method is illustrated with an artificial homogeneous slope and a real slope engineering case. The influence of stabilizing pile installation locations on the reliability results were studied. The sensitivity of random variability was also investigated. The results of the proposed method show high accuracy while having a smaller computational time requirement when compared with the polynomial response surface method. The case study of a real highway slope shows the feasibility of the proposed method applied to practical engineering problems.

“…Yao et al 19 proposed a multi-objective optimization design framework for landslide reinforcement with antislide piles by considering the Majiagou landslide reinforced with anti-slide piles as a case study. They evaluated the stability of the landslide-pile system, and employed the Pareto optimal method to obtain the optimal design scheme.…”

A multi-objective optimization evaluation model for seismic performance of slopes reinforced by pile-anchor system

The significance means of the seismic reinforcement effect of a pile-anchor system for slope reinforcement has been widely recognized. However, cases of deformation failure and instability sliding of the pile-anchor system itself and the reinforced slope under seismic action continue to be recorded. Therefore, it is crucial to evaluate the seismic performance of slopes reinforced by a pile-anchor system to prevent the system’s failure. Current evaluation models of a slope reinforced by a pile-anchor system mainly focus on slope stability; however, the safety of the pile-anchor system itself is not sufficiently considered in these models. Consequently, in this study, we propose a multi-objective optimization evaluation (MOE) model for evaluating the seismic performance of slopes reinforced by a pile-anchor system that considers slope stability, safety of the pile-anchor system, and dynamic response of the slope. This model considers slope displacement, acceleration amplification factor of a slope, pile displacement, and anchor displacement as negative indexes, and anti-slide pile bending moment, shear force, and anchor axial force as intermediate indexes. The comprehensive weight of relevant indexes is obtained by combining subjective and objective weights, and the seismic reinforcement effect of the pile-anchor system is evaluated subsequently. In conclusion, the MOE model proposed in this study provides a novel solution for the optimization evaluation of a slope reinforced by a pile-anchor system in forthcoming projects.
