Gravity inversion of deep-crust and mantle interfaces in the Three Gorges area
Geodesy and Geodynamics, 2012 To better understand the heterogeneity of deep-crust and mantle interfaces in the region of the Three Gorges, China, we used the Parker-Oldenburg iterative inversion method to invert existing Bouguer gravity data from the Three Gorges area (1 : 500000 ...

Depth resolution in potential field inversion: theory and applications
, 2013 One of the principal difficulties with the inversion of the potential field data is the inherent non-uniqueness. In fact, by Gauss' theorem we know that there are infinitely many equivalent source distributions that can produce a measured field (Blakely,

Development and interaction of segmented fault systems
, 1998 Faults in contractional and extensional settings have been studied, both during fieldwork and from interpretation of 2D and 3D seismic sections. Detailed analysis of the geometries of faults, with displacements of a few mm to 100's m, has provided ...

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 ...

Plant adaptive strategies respond to environmental change across European grassland habitats
Ecography, EarlyView.Grassland ecosystems are facing rapid and ongoing change driven by intensified land‐use and accelerated climate change, highlighting the urgent need to understand their potential adaptation and response to environmental change. We analyzed data from 52 980 vegetation plots spanning all major grassland habitats in Europe (including alpine, rocky, sandy,
