在用704 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。

ABSTRACT: In the condition of using binders such as 704 silicagel ,black2and2white glue and plaster ,bolt s 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 bolt s is relatively suitable for fixation of sensors. At the peak vibration ve2
locity as little as about 5mm/ s ,sandbags can be used for fixation of sensors. The binding method with plaster is unfeasible.
KEY WORDS : Vibration monitoring ; Sensor ; Binder ; Fixing way ; Error of datum
