And according to the relation between rock occurrence of the underground chamber and geometricalboundary of excavation, the paper gave the method to positioning breakage.
并根据洞室围岩产状与开挖几何边界的关系，提出围岩易破坏点的位置确定方法。
2
As long as the actual geometrical sizes and boundary conditions of the simulated field, the electrostatic field distribution can be obtained.
只要给出模拟场的实际几何尺寸和边界条件，即可通过计算机得到静电场分布。
3
Then it analyzed the boundarygeometrical intersection method suitable for a polyhedral model, and further presented a hybrid algorithm that integrates model reconstruction.
