摘要(Abstract):

在复杂环境下爆破振动不仅容易引发民事纠纷,甚至会造成安全生产事故,因此,最大限度降低爆破振动对被保护物的影响则显得尤为重要。通过爆破案例分析,以爆破施工对周围房屋损伤影响鉴定为基础,统计与分析不同振动速度对房屋非结构性损坏的影响,研究了振动速度与非结构性损坏之间的规律,并初步确定了振动速度的安全阈值。研究结果对科学、客观的监测与评估房屋损伤具有重要意义。
Blasting vibration in a complex environment is not only easy to cause civil disputes,but even cause safety production accidents.Therefore,it is particularly important to minimize the impact of blasting vibration on the protected object.Through the blasting case analysis,based on the identification of the impact of blasting construction on surrounding houses,statistics and analysis of the effects of different vibration speeds on non-structural damage to houses.The law between vibration velocity and non-structural damage is studied.The safety threshold of the vibration speed is initially determined.The results have important implications for scientific and objective monitoring and evaluation of housing damage.
