Research on Stability Evaluation of Perilous Rock on Soil Slope Based on Natural Vibration Frequency

Perilous rock instability on the soil slope brings a substantial threat to project operation and even people’s lives. The buried depth of perilous is challenge deal with primarily determines its stability, indirect rapid identification key stability evaluation. paper aims find new quick method measure solve hard-to-measure When damping ratio less than one, deformation linear elastic throughout amplitude range, potentially vibration model may reduce multi-degree-of-freedom one. By theoretical deduction, quantitative relationship established among mass, basement response coefficient, rock, natural horizontal frequency. In addition, accuracy this confirmed via numerous indoor experiments, showing that frequency in one dimension increases as increases. Finally, based guided by limit balance model, evaluation constructed. Hence, example shows feasible. research findings are vital significance for give novel approach foundation monitoring.
