The width and buried depth of hidden cracks in tunnel lining are important indicators for
measuring the development degree of crack propagation, and evaluating the risk of lining …

Ground penetrating radar (GPR) has been widely used for detecting cavities and other
hidden defects behind reinforced shield tunnel linings. Migration can collapse diffractions …

Ground penetrating radar (GPR), as a recognized non-destructive testing method, has been
widely applied to detect hidden defects behind a reinforced shield tunnel. However, the …

Accurate extraction of tunnel lining is crucial for deformation monitoring, damage detection,
and tunnel modeling. However, the extraction of tunnel lining is still challenging due to the …

To accurately identify the potential contact loss of the China railway track system (CRTS) III
prefabricated slab track, a finite element model with contact loss of self-compacting concrete …

Relatively low ground-penetrating radar antenna frequencies are usually selected for tunnel
inspection due to the thickness of the lining, which causes the geometric features of voids in …

Effective placement and compaction of the concrete mixture within the spans of prestressed
bridges are essential for the proper anchoring and prestressing of tendons. The high density …

This paper introduces an alternative approach for detecting cavities in reinforced concrete
walls using Ground Penetrating Radar (GPR) A-scan data. GPR, leveraging electromagnetic …

During the actual construction of tunnel sidewall lining, construction workers often use only
one or two windows per layer for pouring in order to reduce the construction sequence …

Abstract The Ground Penetrating Radar method is used to study a three-layered model of
the surrounding rock–void–lining interface with regard to variation in the void thickness and …
