Excavation method of highly-steep vertical toppling deformation side slope
The invention provides an excavation method of a highly-steep vertical toppling deformation side slope. The method includes the following steps that the side slope is excavated to the vertical section of a slope toe; tunnels are excavated in a horizontal partitioning and vertical layering mode; rock benches among the tunnels are arranged in advance; reinforcement is performed; and tunnels in the vertical section of the side slope are excavated. Large rock benches are reserved among the tunnels of the vertical section of the side slope as much as possible so that a retaining structure can be formed; the side slope has no bad deformation features, and it is required that the overall stability of the side slope is kept in the process of excavating the multiple large-diameter tunnels in the slope toe position; the deformation features and stability of the toppling deformation side slope are guaranteed through the schemes of adopting the layered and partitioned excavation modes, keeping the rock benches of the vertical section of the slope toe, reserving rock plugs and the like, and the requirement for the construction period and the requirement for permanent stability in the operating period are met.
