根据对奇梁洞洞穴实地测绘,选取典型断面进行分析,应用有限元程序FLAC3D分析爆破振动对奇梁洞地质遗迹可能产生的影响.模拟计算静力作用和动力爆破振动速度,按照古迹振动标准0.2~0.4cm/s,推算安全爆破控制总炸药量557.6kg,确保奇梁洞地质遗迹的安全.图6,表3,参16. Based on the field survey of Qiliang Cave and the typical section, the finite element program FLAC3D is used to analyze the possible impact of blasting vibration on the geological relics of Qiliang Cave. The static and dynamic blasting vibration velocities are simulated and calculated according to the historic site vibration standard 0.2 ~ 0.4cm / s, calculate the total amount of explosives control safe blasting 557.6kg, to ensure the safety of the geological remains of the Qiliang Cave Figure 6, Table 3, Senate 16.
