Method of reinforcing slope reverse analysis technique

摘要

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 recovered and restored to its own natural state by introduction and application of an earth reinforcement theory, where apparent cohesion is increased by reinforcement members. This slope reinforcing method includes the steps of: determining application conditions in connection with an applicable limit based on soil parameters using the reverse analysis technique of the Janbu method; analyzing the stability of the slope using the Janbu soil parameters to obtain an estimated slip failure force and a resistance force of the slope; defining a construction section of a reinforcement zone in order to increase the resistance force of the slope; disposing horizonal slope drain holes based on underground water level conditions 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 shear capacity of the reinforcement member; preparing design drawings; carrying out the reinforcement construction work; and treating surfaces with greening soil.
