“…In this section, gprMax based on FDTD is used to simulate the process of GPR lining detection. This software is widely used to simulate the propagation law of electromagnetic waves in isotropic homogeneous bodies [26][27][28][29][30]. To save calculation time and facilitate the investigation of the influence of a single factor, the forward simulation is based on the following assumptions.…”

“…Zhang et al 17 used a rectangular member with load-induced cracks as a substitute for cracked tunnel segments to study the relationship between the residual strength and rust layer morphology. Hu et al 18 similarly studied the rust layer distribution of tunnel lining with pre-existing cracks under DC current and chloride ion. However, the transverse cracks and distribution form of rebar in the model test were unlike those of tunnel segments.…”

“…Zhang et al 32 used a rectangular member with load‐induced cracks as a substitute for cracked tunnel segments to study the relationship between the residual strength and corrosion rate. Hu et al 33 similarly studied the mechanical behavior of a tunnel lining with pre‐existing cracks under rebar corrosion. However, the transverse cracks and distribution form of rebar in the model test were unlike those of tunnel segments.…”
