为评价和改进现有土层应力(变)测报地震方法,清理土应力手段,华东片六月二十七日至七月二日在安徽汤口召开土层应力(变)业务技术讨论会。山东、江苏、河南、安徽、浙江、上海的专群地震工作者参加了会议。参加会议的还有国家地震局及所属地霞地质大队、581厂以及四川、云南、河北、北京、天津的代表。会议收到26篇专题报告和论文,涉及以下四个方面内容:1.土层应力观测机理和模拟方面的试验;2.前兆分析和干扰排除方法;3.土层应力观测方法探讨;4.土层应力传感器的测试仪器的研制的改进。会议认为自1970年地震系统提出“应力下山”问题以后土层应力(变)观测得到的迅速发展的普及。在这方面原兰州地震大队、地质力学所、地震地质大队等单位为发展我国土层
In order to evaluate and improve the method of measuring and reporting the existing soil stress (change), and clearing earth stress measures, Huadong film held a technical seminar on soil stress (variation) business in Tangkou, Anhui Province from June 27 to July 2. Specialists from Shandong, Jiangsu, Henan, Anhui, Zhejiang and Shanghai participated in the conference. Also participating in the meeting were the State Seismological Bureau and their subordinate Xia Geological Brigade, 581 Plant and representatives of Sichuan, Yunnan, Hebei, Beijing and Tianjin. The meeting received 26 thematic reports and papers, covering the following four aspects: 1. Soil stress observation mechanism and simulation tests; 2. Precursor analysis and interference removal methods; 3. Soil stress observation methods; Improvement of Testing Instrument for Soil Stress Sensor. The meeting considered that the rapid development of soil stress (change) observed since the earthquake system put forward the “stress downhill” problem in 1970. In this regard, the former Lanzhou earthquake brigade, Institute of Geomechanics, seismic geology brigade and other units for the development of our soil
