摘要
为了研究烟囱类高耸建(构)筑物塌落触地所诱发的地震波振动速度的变化规律,利用实地量测的塌落振动数据,采用量纲分析和最小二乘法,拟合得到建(构)筑物倒塌触地振动速度的估算公式。通过实践论证表明,只要确定了塌落体的质量、质心高度,用该公式就能预测出塌落建(构)筑物到某一定距离处的振动速度。
In order to study the variation law of seism wave vibration velocity caused by collapse of high building such as chimney, the emprical formula of collapse vibration velocity was obtained with dimension analysis and least square method, based on the vibration velocity data monitored. The practice proved that the emprical formula can calculate the ground vibration velocity value of the location which is a certain tance to the collapse site of building, if the mass of collapse building and its center of mass height is determined.
