Optimization of local seismic network layout based on seismic monitoring capability

In order to solve the problem of station location with constraints, the optimization theory of public service facility location is used for reference, and the constituent elements of seismic network monitoring capacity are deeply analyzed, the constraints such as terrain slope, environmental noise level and station layout are also added. Finally, the optimization model of station network layout based on the seismic detection capacity, the recording capacity and the positioning accuracy is established in this paper. Taking the seismic network in Chengdu as an example, the network layout optimization scheme that meets the seismic monitoring capacity requirements of focus and non-focus monitoring areas respectively are obtained by the use of simulated annealing algorithm. And the geographical location of new or newly-built monitoring stations is clearly given.
