摘要
如何在城区环境复杂条件下进行高架桥的爆破拆除并确保爆破安全,成为城市改扩建过程中亟待解决的难题。以南京市城西干道水西门高架桥爆破拆除工程为例,结合振动监测数据分析,通过高架桥爆破拆除过程中产生的爆破振动和塌落振动的对比研究,得出塌落振动强度与塌落体下落高度的关系,以及塌落振动衰减的一般规律,并提出了降低塌落振动的可行方法,可为类似工程提供参考。
To make the controlled blasting demolition of viaducts in complex urban environment safely has become a hard problem needing to be settled urgently in some urban reconstruction and extension projects.Taking the blasting demolition project of the ShuiXiMen viduct in the west main roads of Nanjing for example,combined with monitor vibration data analysis of the relation between collapse vibration strength and height of the collapse building,collapse vibration attenuation rules was obtained based on the comparison between blasting vibration and collapse vibration in the course of viaduct blasting demolition,and some feasible methods of reducing vibration have been put forward,which could offer reference for future similar projects.
