The criticalpressure and conditions of drilling hole burst are determined through the physics experiment of drilling hole burst.
通过钻孔冲击物理试验,研究了钻孔冲击的临界压力,以及钻孔冲击的条件;

The software RFPA is used to simulate the borehole burst, validate criticalpressure, and research the stress drop and acoustic emission before and after occurring the burst in the borehole.
The effect of the initial geometrical imperfection on the buckling criticalpressure and buckling model has been taken into account in the finite element simulation.
