Introduction

Strong motion observations have made important contributions to the development of earthquake engineering, and the proposal and development of the response spectrum theory Based on the acquisition and accumulation of speed records. With the rapid development of strong motion observation technology, the scope of its application is constantly expanding. Use strong motion observation technology to carry out rapid earthquake intensity reporting, earthquake early warning for major projects, and health monitoring of engineering structures, so as to make decisions for earthquake prevention and disaster reduction in our country Provided important technical support. In recent years, my country has learned strong motion observation experience and lessons from major earthquakes such as Wenchuan, Lushan, and Jiuzhaigou, and achieved strong motion observation operations. A new understanding of the impact of operational maintenance work on the quality of strong motion records, scientific and standardized operation and maintenance work will better ensure the quality of strong motion observations. quality of data. At present, social and economic needs have promoted the further expansion of the scale of strong motion observation in my country, and national and local governments, large national Enterprises have built a large number of strong motion observation stations. However, there has been a lack of scientific and standardized guidance for the operation and maintenance of large-scale strong motion observations. Therefore, it is urgent to provide the operation and maintenance, data output, and related work technical requirements and methods of strong motion observation to help the strong motion observation business. standardized and efficient operation. This document is based on the operation and maintenance work foundation of my country's strong motion observation network for many years, combined with the earthquake monitoring business of China Earthquake Administration in recent years It is formulated according to the requirements of the guidelines for the structure and reform of seismic stations. Seismic Network Operation Standards for Strong Motion Observation

1 Scope
