Abstract: In order to study the andesitic porphyrite failure rule of open-cut blasting in diversion tunnel of reservoir, taking the Qianping reservoir project as an example through blasting test and vibration detection, field observation, statistical analysis and numerical simulation, the blasting technology of open cut diversion tunnel of reservoir is studied. Finite element method software ANSYS was used to establish the finite element calculation model of open cut diversion tunnel of Qianping reservoir. The andesitic porphyrite blasting process is simulated by using the dynamic analysis module LS-DYNA in ANSYS. The simulation results are compared with the test results, determining the optimal design scheme for open cut blasting of diversion tunnel. Numerical analysis and test results show that andesitic porphyrite blasting excavation is suitable for blasting parameters in I-2 area. The three-dimensional numerical model, firstly established in this paper, can be used to guide similar blasting schemes. The research results are of guiding value to similar projects.
