Complex variable solution on over-/under-break shallow tunnelling in gravitational geomaterial with reasonable far-field displacement
Luo-bin Lin, Fu-quan Chen, Jin-ping Zhuang
Over-/under-break excavation is a common phenomenon in shallow tunnelling, which is nonetheless not generally considered in existing complex variable solutions. In this paper, a ne…
A new complex variable solution on noncircular shallow tunnelling with reasonable far-field displacement
Luo-bin Lin, Fu-quan Chen, Shang-shun Lin
A new mechanical model on noncircular shallow tunnelling considering initial stress field is proposed in this paper by constraining far-field ground surface to eliminate displaceme…
Reasonable mechanical model on shallow tunnel excavation to eliminate displacement singularity caused by unbalanced resultant
Luobin Lin, Fuquan Chen, Xianhai Huang
When considering initial stress field in geomaterial, nonzero resultant of shallow tunnel excavation exists, which produces logarithmic items in complex potentials, and would furth…
Parallel generalized solutions of mixed boundary value problem on partially fixed unit annulus subjected to arbitrary traction
Luobin Lin, Fuquan Chen, Xianhai Huang
This paper provides two parallel solutions on the mixed boundary value problem of a unit annulus subjected to a partially fixed outer periphery and an arbitrary traction acting alo…
