Firstly, field investigations and measurements of rock and soil mechanics parameters were carried out for typical tunnel engineering sites. Secondly, based on finite element simulation and three-dimensional mechanics analysis software, numerical simulations of the surrounding rock and soil under different stress states were conducted, and the tunnel support structures were optimized in design and mechanically analyzed. Finally, the effects of different stress states on tunnel support structure design were analyzed and compared, and some optimization suggestions were proposed. Keywords: tunnel engineering, rock and soil, stress state, numerical simulation, optimization design, mechanical analysis.
