长治地震台电感地应力是一九七○年八月由地震地质大队负责钻孔并安装元件,九月开始正式观测。孔深109米,井下安装四个元件,受力元件L_1N60E、L_2NsL_3 N60W,悬空元件Lo。孔位于新华夏系晋(城)获(鹿)大断裂的中段,岩性为中奥陶石灰岩,测试仪器是广州华南机械厂研制的LQJ—1A型精密电感电桥。 通过两年多的观测与地震三要素的对应分析认为电感曲线的异常对平遥、太谷、和顺、昔阳及河北邢台、行唐地震有较好的反应。 毛主席教导我们:“实践的观点是辩证唯物论之第一的基本的观点”。“要认真总结经验”。在实践的基础上,现将我台电感地应力予报工作中的几点体会整理如下:
Changzhi Seismostat inductive ground stress is in August 1970 by the seismic geology brigade responsible for drilling and installing components, began in September formally observed. Hole depth of 109 meters, downhole installation of four components, force components L_1N60E, L_2NsL_3 N60W, dangling components Lo. The hole is located in the middle section of the (deer) large fault in Jinhua (city) of Xinhuaxia. The lithology is the middle Ordovician limestone. The test equipment is the LQJ-1A precision inductance bridge developed by Guangzhou South China Machinery Factory. After more than two years’ observation and corresponding analysis of the three elements of the earthquake, it is considered that the abnormality of the inductance curve has a good response to Pingyao, Taigu, Heshun, Xiyang, Xingtai, Xingtang and Xingtang Earthquakes in Hebei. Chairman Mao teaches us: “The practical point of view is the first basic point of view of dialectical materialism.” “We should conscientiously sum up experience.” On the basis of practice, now my station stress to report to the work of the experience compiled as follows:
