Outline
In order to ensure the normal passage of vehicles and the safety of the existing tunnel support structure during the blasting through the highway，the evaluation method of engineering blasting effect based on extension-AHP model was proposed. Firstly，by means of investigation and analysis，the blasting effect rating standard and index system were established，and the model was applied to the evaluation of a water diversion project. Secondly，AHP was used to determine the weights of evaluation indexes，and the combined relevance degree of blasting rating was calculated. Finally，the results of the blasting effect rating were verified by acoustic detection test，blasting shock wave test and blasting seismic wave test. The study shows that the combined relevance degree is calculated by extension-AHP model. The blasting effect of the tunnel boring is Qmax=-0.017，and the evaluation grade is a good blasting effect. The surrounding rock loose circle of the tunnel is relatively small and evenly distributed. The influence range of the surrounding rock stability is about 0.5-0.6 m. The blasting energy does not cause the rock rupture zone to further extend the signs of the inward. The energy attenuation trend of blasting seismic waves is different under different wave frequencies. However，the attenuation rate is greater than that of low-frequency component energy in the overall performance of high-frequency component energy. In the same channel，with the increase of the distance between the blasting source and the measurement points，the overall vibration waveform becomes narrower. The main frequency increases first and then decreases，and the main frequency domain moves to the low-frequency direction. The overpressure peak attenuation characteristic of blasting shock wave meets PS=αl-γ. With the increase in the distance from the blasting source，blasting shock wave overpressure attenuation coefficient is an increasing trend. The measurement range belongs to the shock wave attenuation zone. The shock wave overpressure peak of the tunnel entrance and the construction outside tend to converge.
