Abstract

The proper excavation sequence of comprehensive strengthening remolded soil method of combining sleeve-valve-pipe grouting and bolt support was studied for the abutment backfill stability problems when the retaining wall in front of pillar abutment was excavated which was often encountered in the construction process of highway reconstruction and extension. With ANSYS software, the strength reduction method was used to analyze the safety factor of slope excavation of different excavation programs to determine the most rational excavation program.
