Abstract: Through the collection,research and analysis of large amount of blasting earthquake data,a corresponding model of blasting earthquake simulation signal is set up.The blasting earthquake simulation signals are applied to analyze the dynamic response of high retaining wall structure under blasting earthquake wave.Using the technology of instantaneous kinetics analysis,the dynamic response and control limit vibration velocity of structure are got,which provides necessary technical parameters for blasting earthquake monitoring of high retaining wall structure.

Key words: high retaining wall structure, earthquake wave, blasting earthquake simulation signal, instantaneous mode analysis, blasting earthquake monitoring
