Research on Open Cut Blasting Technology of Reservoir Diversion Tunnel

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