一、台站环境及地热仪器概况昌平地震台地热观测孔位于十三陵风景区的卧虎山下,地处阴山巨型纬向构造带的南沿,北东向南口山前活动性断裂和北西向南口-孙河活动性断裂交叉部位东侧的7.5km处。观测孔在震旦纪碳酸岩裂隙潜水区,目前水位高度44m。东北山区为补水区,所以地下水由东北流向西南。水温梯度极小,百米温差小于0.1℃。该孔深102m,井孔密封良好。1995年12月安装SZW-1A型数字式温度计一台,探头埋深99m。该仪器自安装以来一直运行良好,产出了大量有效数据。该孔的地热观测资料对昌平台周围300km范围内的多次地震震前均有异常反映。2001年7月在该孔内又安装了
First, the station environment and geothermal equipment Overview Changping Seismological Observatory geothermal observation hole located in the Ming Tombs Scenic Area lying Wo Hu, located in the Yinshan giant latitudinal zonal belt along the south, north-east southbound active fault and the northwest South exit - Sunhe active fracture intersection east of 7.5km. Observation hole in Sinian carbonate rock fissured diving area, the current water level of 44m. Northeast mountain water area, so the groundwater flow from northeast to southwest. Water temperature gradient is extremely small, 100 meters temperature difference is less than 0.1 ℃. The hole depth of 102m, bore well sealed. 1995 December SZW-1A installed a digital thermometer, probe depth of 99m. The instrument has been operating well since its installation and has produced a large amount of valid data. The geothermal observation data of this hole all have anomalous reflection on many earthquakes within 300km around Changping platform. July 2001 installed in the hole again
