【摘要】 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.更多还原

【Abstract】 Based on the survey on the spot and selection of typical section,FLAC3D software was applicated to analysis the influence degree of blasting vibration to geological heritage which possibly produces to the Qi-liang cave.Using finite-element procedure FLAC3D,blasting vibration velocity was studied by means of numerical simulation under static situation and dynamic conditions.The total blasting explosive charge was calculated precisely on the basis of calculation results obtained from simulation.Finally,the suggestion was given to protect geological heritage on condition that the explosive charge is controlled normally according to the standard.6figs.,3tabs.,16refs.更多还原
