基于GTS的深埋隧洞开挖支护数值模拟

Sets in the background of Shiziping Hydropower Station in Li County of Sichuan Province, to carry out a numerical simulation of the excavation support of the pressure pipeline in edit section by implying MIDAS/GTS, and to calculate the displacement of surrounding rock and other physical quantity such as bolt stress, finally to make a judgment of the stability of the surrounding rock, and to give a guidance of the implementation of the pressure pipelines., and for the relevant engineers to provide empirical data.
