Method for reinforcing slope reverse analysis technique

Abstract

Disclosed is a method for reinforcing a slope, in which field ground deformation characteristics of an unstable slope can be rapidly and reliably judged, and the unstable slope is recovered and restored to its own natural state so as to make it possible to secure stability by introduction and application of an earth reinforcement theory, i.e., a theory that an apparent cohesion is increased by reinforcement members. This slope reinforcing method comprises the steps of: studying application conditions in connection with an applicable limit, in consideration of which determining soil parameters using the reverse analysis technique of the Janbu method; analyzing stability of the slope using the soil parameters by the Janbu method to estimate an slip failure force and a resistance force of the slope; planning a construction section of a reinforcement zone in order to increase the resistance force of the slope; disposing slope horizontal drain holes in consideration of the underground water level condition to study an external stability; checking an internal stability within the reinforcement zone against a critical failure; section in consideration of a pull-out force and a shear capacity of the reinforcement member; preparing design drawings; carrying out a reinforcement construction work; and treating surfaces of the greening soil.
