通过对一片砌体墙进行数值模拟,采用地铁隧道施工沿线爆破的振动现场实测振动数据,并进行调幅,对比分析墙体的破坏规律。通过分析结果评价隧道爆破施工对建筑物产生的破坏影响,并探讨爆破施工过程中安全的控制振速。
This paper with a study of the numerical simulation of a masonry wall takes vibration field measurement of vibration data along the subway tunnel construction blasting,and amplitude modulation to compare and analyze the law of the wall damage.By analyzing the results of evaluation of tunnel blasting construction damage effect on buildings,it discusses the blasting safety control of vibration in the process of speed.
