TL;DR: In this paper, a nonlinear finite element method (FEM) analysis technique is developed to simulate the viscous behavior of geogrid-reinforced sand during loading.

TL;DR: In this article, a new elasto-viscoplastic constitutive model for sand is proposed, formulated based on a stress path-independent irreversible (or visco-plastic) strain energy-based hardening function.

TL;DR: Wang et al. as discussed by the authors analyzed the planning motivations, characteristics and current challenges of complex underground roads for motor vehicles with typical examples in Chinese cities and provided a 5-step procedure of overall layout planning and an integrated planning strategy.

TL;DR: In this paper, the authors explored the categories of environmental externalities tailored to UUFs, considering both environmental contributions and losses, and the framework of the replacement/restoration cost method (RCM) was employed to measure the externalities of urban underground facilities in monetary terms.

TL;DR: In this paper , the authors focus on how UUS use benefits urban development, and pay particular attention to the potential threats posed by underground space use to urban sustainability, and demonstrate that the distribution of positive socio-environmental externalities derived from UUS uses was consistent with the planning visions of boosting and revitalizing local development.
