Introduction

Since the implementation of DB/T 17-2006 "Seismic Station Construction Specification Strong Motion Stations", it has guided the construction of strong motion stations in my country, especially It is the construction of the national digital strong motion network to ensure the quality of strong motion observation data. On May 12,.2008, Wenchuan 8.0, Sichuan On April 20,.2013, a large number of high-quality strong motion records were obtained from the earthquake of Lushan, Sichuan with a magnitude of 7.0, which was used for engineering seismic fortification and seismic science. The research provided reliable record data and achieved good social benefits. This revision is mainly based on the following reasons. ---From the magnitude 8.0 earthquake in Wenchuan, Sichuan on May 12,.2008, and the magnitude 9.0 earthquake in the Northeast Pacific Ocean off Japan on March 11,.2011 Obtained a wealth of strong motion observation experience in major earthquakes at home and abroad; ---Based on the analysis of a large number of strong motion record data in my country, new understanding of the impact of strong motion station construction on the quality of observation data has been obtained; --- Important progress has been made in the construction of new schemes, new technologies, new processes and new equipment for strong vibration stations at home and abroad, and is gradually being applied; ---In addition to the earthquake industry, nuclear power plants, large dams, high-speed railways, long-span bridges and other related industries and some local governments are also The station construction puts forward new demands. In this revision process, the following factors were mainly considered. ---Strict regulations on the key links that affect the quality of strong motion observation data, such as standardizing the construction requirements and dimensions of the observation room and instrument piers, and giving examples; --- Weigh and coordinate construction costs and construction quality, control key aspects of quality control, reduce capital investment in ancillary facilities, and strive to To ensure quality and reduce costs, maximize the number of strong motion stations to increase the number of high-quality strong motion observation data. Seismic Station Construction Specification Strong Motion Station
