摘要
在工程爆破施工中不可避免对邻近房屋会有振动影响,作者通过对一公路隧道石方爆破振动效应观测报告的分析,结合多条高速公路爆破施工对房屋振动影响的调查,探讨了爆破施工对房屋振动影响与振源距、炸药量的关系,提出了房屋结构安全允许的振动参数建议值。
The effect of the vibration happening in the blasting construction can not be avoided to the nearby buildings. Based on the analysis of the report about blasting vibration effect of a highway tunnel, combining with the surveys of the influence of highways blasting construction to the buildings, the influence of blasting construction to the buildings, and connection with the distance of vibration center, the capacity of explosive are discussed. And the permitting parameters of vibration for buiMing structure are proposed.
