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 ...

User Perception on Urban Light Rail Transit [PDF]

Civil Engineering and Architecture, 2019
Public transport is a shared passenger transport service available for public use. Increased population is accompanied by the increased demand for private vehicles. The exponential growth in the number of private vehicles will result in negative impacts such as air pollution, excessive noise, and traffic congestion. Additionally, customers’ perceptions

Collective Decision‐Making and Institutional Configurations in Polycentric Environmental Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Why do formally similar multi‐level governance arrangements produce different governance outcomes in urban climate and transport policy? This article examines variation in governance performance across three metropolitan regions in Norway operating under the national Urban Growth Agreement (UGA) framework and pursuing the shared objective of ...
