摘要:
为了避免和减少隧道爆破振动及噪声对复杂敏感环境城区的影响，以珠海板障山新增隧道为例，采用数值模拟和现场爆破试验的方法，对不同掏槽眼延期时间下既有隧道迎爆侧进行爆破振动监测。发现掏槽眼延期时间4 ms时，既有隧道迎爆侧爆破振速最小。同时，针对隧道进口段周边建筑物繁多、爆破噪声大、飞石迸溅的问题，进行了炮孔封堵和防飞石的试验。设计发明了一种新型炮孔堵塞装置，在装药量增大情况下，爆破噪声能够控制在允许范围内。在洞口采用联合防护门帘，减少了飞石迸溅的风险。可为复杂敏感环境城区隧道爆破振动和噪声控制提供参考。
Abstract:
In order to avoid and reduce the impact of tunnel blasting vibration and noise on complex and sensitive urban areas, taking the newly built Banzhangshan Tunnel in Zhuhai as an example, numerical simulation and field blasting tests were used to monitor the blasting vibration on the blasting side of the existing tunnel under different delay times of cut holes. When the delay time between the cut holes is 4 ms, the blasting vibration velocity on the blasting side of the existing tunnel is the smallest. At the same time, aiming at the problems of numerous buildings around the entrance section of the tunnel, high blasting noise, and flying stones splashing, experiments of gun hole plugging and anti-flying stone was carried out. A new type of gun hole plugging device was designed. When the charge increases, the blasting noise can be controlled within the allowable range. The use of joint protective door curtains at the entrance reduces the risk of flying stones splashing. It provides a reference for the control of blasting vibration and noise in urban tunnels in complex and sensitive environments.
