To analyze and evaluate the influence of the
geological environment on the construction of tunnel engineering, investigation
and analysis are conducted on the engineering geological conditions such as the
topography and geomorphology, regional geological structure, stratum lithology,
hydrogeology, and insitu stress of the tunnel site, and
the analytic hierarchy process is used to evaluate the quality of the tunnel
site. The research results show the following: (1) Affected and controlled by
the geological factors such as topography, geological structure, stratum
lithology, hydrogeology, and insitu stress in the
tunnel site, the surrounding rock of the tunnel performs broken, waterrich, soft, and weak. Bad geological phenomena such as mud inrush,
collapse, and large deformation of soft rock are easily occurred during
construction process. (2) The comprehensive evaluation value of the Xinping
tunnel site′s superiority and inferiority grade is
1.31, and the site′s superiority and inferiority grade
is extremely poor, indicating extremelyhigh risk. (3)
The reveled surrounding rock levels and geological disasters show the accuracy
and reliability of the evaluation method and results of the tunnel site′s superior and inferior grade.
