ABSTRACT: In order to ensure the safety of coal mine shaft construction, a
double-layer steel plate concrete composite shaft wall structure was proposed.
However, fewer studies were conducted on this structure, which made engineers
too confused to fully recognize its feasibility of this structure. Hence, based
on the previous experimental research on the Taohutu mine construction project
in Ordos in Inner Mongolia, this
research paper aims to provide a widely deep numerical analysis by the usage of
the finite element software, in fact, to establish
the corresponding numerical analysis model and make a comparison with
the experimental data to get the rationality of the verified model. The influence
of the composite characteristics of the steel plate and concrete on the
ultimate bearing capacity and stress field of the shaft wall structure is
studied here through the method of multi-factor analysis. Also, the optimal
design scheme of the double-layer steel
plate and concrete composite shaft wall structure is proposed in this
research paper.
