临近既有线隧道开挖控制爆破试验与振动测试

Control Blasting Experiment and Vibration Test during Adjacent Tunneling Close to Exiting Tunnel

依托南平-龙岩铁路线的斑竹垄隧道工程,通过现场控制爆破试验与振动测试及其结果分析,同时结合相关研究成果,通过类比分析爆破振动衰减规律,论述了斑竹垄隧道控制爆破钻爆参数选取与确定的合理性与可行性,相关研究成果应该可为类似工程控制爆破接近施工提供参考和借鉴.

Based on Banzhulong tunnel project of the Nanping-Longyan railway line, blasting vibration simulation test on site is analyzed in this paper. The procedure of analysis is combined with domestic exist- ing research norms, results and the blasting vibration test. At the same time, compared with the attenuation law of blasting vibration on similar projects, blasting tunnel near the exiting railway are evaluated. The results of design par the analys when the Banzhulong tunnel is excavated. And it＇s also can provide a ameters＇ rationality of Banzhulong is are used to guarantee the security useful reference for the similar project.
