“…In previous numerical studies [19][20][21][22][23][24], there have been few studies on the impact of overburden thicknesses on the structural cracking risk. Figure 9 shows the longitudinal tensile stresses of the structure under different overburden thicknesses when the grade of rock and soil mass is IV.…”

“…It is currently a commonly used method for studying structure cracking risk. Based on the load-structure method, the effect of strata on the structure is simplified as the load acting on the structure [19,20]. Huang et al [21] established a numerical model to analyze the influence mechanism of geological factors and temperature factors, and determined that concrete cracking depends on the maximum tensile stress of the structure.…”

During the operation period of tunnels in urban deep aquifer zones, the geological environment around the tunnel is complex and the surrounding strata are rich in groundwater, which often poses a risk of structure cracking and groundwater leakage, seriously threatening the tunnel’s safety. To reduce the risk of tunnel cracking, a theoretical calculation model and a three-dimensional concrete–soil interaction thermo-mechanical coupling numerical computing model was established to analyze the tunnel structure cracking risk under the influence of multiple factors in urban deep aquifer zones. The response mechanism of structural stress and deformation under the influence of the grade of rock and soil mass, overburden thickness, temperature difference, structure’s length–height ratio, structure’s thickness, and structure’s elastic modulus was investigated, and the stress and deformation response characteristics of the structure with deformation joints were explored. The results show that the maximum longitudinal tensile stress of the structure increases with the increase in the grade of rock and soil mass, overburden thickness, temperature difference, structure’s length–height ratio, and elastic modulus. The temperature difference has the most significant impact on the longitudinal tensile stress of the structure, with the maximum tensile stress of the structure increasing by 2.8 times. The tunnel deformation joints can effectively reduce the longitudinal tensile stress of the structure, and the reduction magnitude of the tensile stress is the largest at the deformation joints, which is 64.7%.

“…Despite its advantages in design flexibility, component integration, and environmental benefits, particularly regarding energy and material efficiency, the application of 3D printing in building renovation, especially façade systems, remains limited and underexplored [18,19]. Although not part of this research, it is worth mentioning that other emerging technologies, such as AI [20], can be used to optimise the design and manufacturing process of 3D-printed elements [21].…”

This paper introduces a novel modular retrofitting solution to enhance the energy efficiency and seismic resilience of building façades, particularly within the Portuguese context. In the context of Europe’s “Renovation Wave” strategy, and as a product of the nationally funded ZeroSkin+ project, the proposed renovation solution addresses the urgent need for sustainable building renovations to help mitigate climate change and meet European climate neutrality goals by 2050. Unlike traditional methods that often rely on non-eco-friendly materials without integrating seismic and thermal performances, the renovation solution leverages fused deposition modelling (FDM) 3D printing technology to introduce a dual-layered panel system. This system features a durable, UV-resistant PET-G thermoplastic outer layer and a cork interior to ensure additional thermal insulation. The integrated renovation solution shows a 42% improvement in seismic reinforcement’s out-of-plane capacity and achieves U-values as low as 0.30 W/m2·K, exceeding Portugal’s thermal efficiency standards (0.35 to 0.50 W/m2·K). The proposed renovation solution also embraces circular economy principles, emphasising waste reduction and recyclability.

“…These calculation models typically only consider soil deformation, and the conditions of adjacent structures are not fully explored. Some cases of damage to surrounding structures caused by foundation excavation Shen et al, 2023;Zhang and Wu, 2014; highlight the need for monitoring and specific consideration of deep foundation pits with complex surroundings in practical engineering. Deformation monitoring of foundation pits, as an important means of preventing and controlling foundation pit construction risks, plays a critical role in avoiding foundation pit accidents.…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.
