在用704 硅膠、黑白膠和石膏等黏結劑、螺栓或沙袋固定傳感器的條件下,分別測定了爆破震動的垂直峰值速度,并對測定數(shù)據(jù)進行了分析和比較。在峰值速度小于3cm/ s 時,用黏結劑(粘結厚度小于2mm) 或螺栓固定傳感器的方法是比較合適的。在峰值速度很小(5mm/ s 左右) 時,用沙袋固定傳感器的方法也可以使用。用石膏粘結的方法不可行。

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.
