浅埋双洞隧道爆破振动安全技术研究
|
摘要
熊冲隧道采用控制爆破法进行开挖,为了控制熊冲隧道爆破振动所产生的危害,采用TC-4850新型爆破测振仪对熊冲隧道爆破振动进行监测;通过收集现场测振数据,分析V-L,V-f之间的关系图,了解地震波在围岩中的衰减特点,利用萨道夫斯基经验公式结合爆破安全规程相关规定对目前的振动安全情况进行评价,并提出了建议。
Controlled blasting is adopted for excavation of Xiongchong tunnel,in order to control the damage caused by blasting vibration in Xiongchong tunnell,the blasting vibration of Xiongchong tunnel was monitored by TC-4850 new blasting vibration meter. This paper collects and analyzes vibration data at site,draw a diagram of the parameters between them,the present situation of vibration safety is evaluated by using sadaovsk empirical formula and the relevant regulations of blasting safety regulations,and made comments.
