Method of strengthen for slope using reverse analysis

摘要

PURPOSE: A method for reinforcing a slant face is provided to perform reinforcement safely and promptly, to easily and promptly analyze the stiffness of the ground proper to a working spot destruction model by applying a reverse analysis and to analyze a slant face stably. CONSTITUTION: Reinforcement of a slant face is performed by the following steps. An internal stability of a reinforcement member to the inner part of a section to be reinforced of a critical destructed section is examined by examining drawing and shearing properties of the reinforcement member. A designed section is determined by considering an external condition of stability and an internal condition of stability. A reinforcement is performed according to the determined design section. The surface of a slant face is processed with a vegetation method by which artificial soil is covered. A stability is secured by the reinforcement of the slant face. An unstable slant face is restored in a natural state or reinforced by a method harmonized with environment. A construction is performed to be proper to the such conditions of a working spot as the deformation or the collapse of the ground.
