Yieldable construction method for early releasing surrounding rock deformation on weak counter-inclined slope

ActiveUS20180010316A1Reducing surrounding rock toppling deformation riskEnsure safetyClimate change adaptationBlastingSlope stabilityGeophysics
The present invention provides a yieldable construction method for early releasing surrounding rock deformation on a weak toppling slope, thereby reducing surrounding rock toppling deformation risk in and after an excavation process and ensuring overall slope stability and safety of a supporting structure. A technical solution of the present invention is as follows: loosing a rock mass through controlled blasting; inducing toppling deformation of the slope by injecting water and softening a blasting relaxation part of the rock mass; determining timing of water injection by monitoring slope surface displacement characteristics of the slope; and performing a normal excavation process of the toppling deformation slope after injecting is completed. The present invention is applicable to design and construction of high slope engineering of a special kind of rocks, i.e., a toppling deformation slope composed of weak rock masses.
