Geological conditions of tunnel Engineering geology conditions.
MIDAS/GTS of South Korea was used as the analysis software, based on the engineering geological investigation report and related specifications of railways and highways, physical and mechanical parameters of the surrounding rock were selected and the results were listed in Table 2.

Although it is no longer the main structural material for spacecraft, it is still widely used in civil industries.
However, since the cost of titaum alloy material is relatively high, currently its engineering application scope is still small.
