［Abstract ］Due to the steep terrain of the mountain tunnel under loose and broken geological conditions ， the construction process
is slow， the construction scheme is complicated， and there is no systematic research on the design and construction technology of
inclined shafts， the construction technology of the inclined shaft into the mountain tunnel under loose and broken geological conditions
is carried out reasonable design analysis and optimization research are essential. In view of the special geographical location and
engineering characteristics of the entrance of Pingtian Tunnel， through the combination of theoretical analysis and actual engineering，
the optimal mountain tunnel construction technology was researched and formulated ， including the inclined shaft entry plan， the overall
entry construction arrangement steps， and the inclined several key schemes， such as the well design scheme and the main construction
scheme of the inclined shaft， have solved the problem of serious shortage of the entry site from the main tunnel， and proposed the reverse
excavation of the small guide tunnel at the entrance of the tunnel section under extremely broken geological conditions ， and solved the
tunnel. The difficulty of digging into the tunnel in the forward direction is provided， and the tunnel ballast transportation channel and
working space are provided， which ensures the construction safety of the tunnel entrance section and provides reference for such projects.
