Carbon emission assessment of tunnel infrastructures: From construction to operation
Deep Underground Science and Engineering, EarlyView.This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology
Deep Underground Science and Engineering, EarlyView.This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Environmental Policy and Governance, EarlyView.ABSTRACT Participatory processes are increasingly recognized as essential components of modern environmental governance. While much scholarly attention has been devoted to the design and implementation of such processes, less is known about the critical phase between participatory processes and final policy outputs.
