Observing Technology System For the Across—fault Deformation Measurement

一、跨断层形变测量的理论基础长期研究表明,地震的发生与断层活动密切相关.构造地震是地球动力学过程的一种表现形式,与活动断层互为因果关系.因而对活动断层进行监测,无疑可获取地震前兆信息.实验和观测表明,断层两侧三度空间的相对运动幅度远大于连续岩体应变信息的幅度.

This paper introduces the observing technology system for the across-fault deformation measurement in its entirety.It presents the theory basis of the across-fault measurement and its important role in the monitoring system of crustal deformation.It also describes briefly the principles of measuring place arrangement,the main technique target of all kinds of observing methods,and so on.In general outline,the paper deals with the development and current situation about the across-fault measurement in our country,which is created in 1960’s and stepping into the trail of specifization and standardization in 1990’s,forming an overall distribution framework which monitors all main active faults,a data system of specified collection and standardized processing,and a united system of technology management,so that improving the depth into the earthquake-prediction research of this subject,and giving out a series of successfully predicted examples.At the end of the paper,the trend of the across-fault deformation measurement in the later is given in brief.
