摘要(Abstract):

在用 70 4硅胶、黑白胶和石膏等黏结剂、螺栓或沙袋固定传感器的条件下 ,分别测定了爆破震动的垂直峰值速度 ,并对测定数据进行了分析和比较。在峰值速度小于 3cm/s时 ,用黏结剂 (粘结厚度小于 2mm)或螺栓固定传感器的方法是比较合适的。在峰值速度很小 (5mm/s左右 )时 ,用沙袋固定传感器的方法也可以使用。用石膏粘结的方法不可行
In the condition of using binders such as 704 silicagel,black and white glue and plaster,bolts or sandbags for fixation of a sensor,the vertical peak velocities of blasting vibration were respectively measured.And measured data were analyzed and compared.At the peak vibration velocity of less than 3 cm/s,the binders(with binding thickness of less than 2mm)or bolts is relatively suitable for fixation of sensors.At the peak vibration velocity as little as about 5mm/s,sandbags can be used for fixation of sensors.The binding method with plaster is unfeasible.
