摘要
为准确分析国家重点工程温福铁路的福建III标段笔架山隧道爆破施工中对邻近的砖混建筑物产生的振动影响,本文对隧道爆破振动效应进行实测,根据实测数据采用时程分析法计算房屋结构的动力响应。结果表明:《爆破安全规程》(GB6722-2003)中安全速度规定是偏于安全的;以实测数据为基础,速度激励的时程分析方法对爆破地震动对房屋的影响进行评价,是一种可行的、较为精确的方法。
In order to analysis the effect of the vibration happening in Bijiashang tunnel blasting construction to a masonry structure house nearby,the data of tunnel blasting construction are measured,and the house dynamic response is calculated by time-history Analysis.The resulf shows that the requirements in safety regulations for blasting（GB6722-2003）are laying a particular stress on safe;base on the data,the house dynamic response is analyzed by time-history analysis.It is a feasible and more accurate method.
