| 摘 要： | 以福州金鸡山隧道拓宽改造项目为背景，为降低爆破振动对邻近通行洞以及周边房屋的影响，通过采用合理的交叉中隔壁（CRD）隧道开挖法、调控药量、掏槽方式布设等措施加以控制。结果表明:监测点爆破振速均未超过限定值，说明控制措施有效。

Analysis of Blasting Control Measures in Urban Tunnel Widening |
| |
| Abstract: | Taking the widening reconstruction of Jinjishan Tunnel, Fuzhou as the background, for the purpose of reducing the effect of blasting vibration on the adjacent access hole and houses, the proper control measures, such as center cross diagram(CRD)tunneling method, explosive quantity regulation and cutting mode arrangement, were used. The result shows that the blasting vibration velocity at the monitoring point does not exceed the limit, and the control measures are proved to be effective. |
