摘要:
随着城市交通的日益拥挤,一些已建成并使用的桥梁因病害、承载能力不足等问题需要被拆除。针对如何减弱桥梁爆破拆除塌落过程对浅埋管线的冲击影响问题,通过高架桥爆破塌落桥体对浅埋管线冲击响应分析,采用数值模拟的方法模拟典型高架桥爆破拆除倒塌过程对地面冲击作用,以及通过浅埋典型管线的抗振模拟试验,提出塌落桥体冲击作用下浅埋管线综合防护原则及关键技术。
Abstract:
With the urban traffic congestion, some bridges have to be demolished due to functional failure and insufficient load capacity. In order to reduce the impact of bridge blasting on shallow buried pipeline, numerical simulation was used to analyze the collapse process of blasting demolition of urban viaduct. Furthermore, in combination with seismic simulation experiment of shallow buried pipeline, the principle and key technology of shallow buried pipeline comprehensive protection are put forward.
