Application of digital accelerograph in dam safety monitoring
Ma Jin-hui Chen Shu-lin · Progress in geophysics · 2009
This paper presents a new type of digital accelergraph (GDQJ-2) for recording strong ground motion of earthquakes. Due to its unique structure and performance, this instrument has been widely applied to earthquake observations and dam safety monitoring. In this article we describe the importance of dam safety monitoring and progress of seismic instruments in this field. We also present the structural principle, technical parameters of the instrument GDQJ-2 and its application to dam safety monitoring, which provide direet basis for design of dam safety code.
