本文试图从DY-1蠕变仪的断层水平活动自记曲线中提取临震信息作一探讨。 资料概况 唐山7.8级大震后,我们先后在北京大灰厂、八宝山和唐山等处,用DY-1型蠕变仪进行断层水平活动的监视试验。各测点分别位于地面以下3米、8米和900米处,按断裂位移型展布测线。为了取得可信的资料,除设置常规方法(基线、水准)的检测装置外,还采用地面相应测线和应变型测线提供验证。发现:各点测值 This article attempts to extract the quake-sensitive information from the horizontal motion self-recorded curve of DY-1 creep meter. Data Overview After the MS7.8 Tangshan earthquake, we monitored the fault level activity with the DY-1 creep meter successively at Beijing Dacheng Factory, Babaoshan and Tangshan. The measuring points are located 3 meters below the ground, 8 meters and 900 meters, according to the displacement of the measured displacement distribution line. In order to obtain credible information, in addition to the conventional method (baseline, level) of the detection device, but also the ground with the corresponding line and strain gauge line to provide verification. Found: the measured value of each point
