Analytical solutions for bolted tunnel structures with voids behind the lining

Understanding the mechanical behaviour of tunnels reinforced by end-anchored bolts and lining with voids behind the lining is crucial in determining the appropriate supporting measures. In this study, we constructed a geometric model for a tunnel with a single or double void. We used the substructure method and point matching method to obtain the elastic analytical solutions for the model. We examined the stress, internal force, and deformation characteristics of the tunnel and support structure under the influence of single and double voids. To validate the analytical model, we established a numerical model using the finite difference method. Additionally, we compared and analyzed the mechanical behaviour of tunnels reinforced by bolts and lining versus lining-only, and determined the contribution factor of the bolts.

期刊介绍： Journal of Taibah University for Science (JTUSCI) is an international scientific journal for the basic sciences. This journal is produced and published by Taibah University, Madinah, Kingdom of Saudi Arabia. The scope of the journal is to publish peer reviewed research papers, short communications, reviews and comments as well as the scientific conference proceedings in a special issue. The emphasis is on biology, geology, chemistry, environmental control, mathematics and statistics, nanotechnology, physics, and related fields of study. The JTUSCI now quarterly publishes four issues (Jan, Apr, Jul and Oct) per year. Submission to the Journal is based on the understanding that the article has not been previously published in any other form and is not considered for publication elsewhere.
