基于地震监测能力的地方测震台网布局优化

Optimization of local seismic network layout based on seismic monitoring capability

  • 摘要: 为解决带约束条件的台站选址问题,本文借鉴公共服务设施选址最优化理论,深入分析测震台网监测能力的构成要素,并考虑地形坡度、环境噪声水平、台站布局等约束条件,建立了基于地震检测能力、记录能力和定位精度的台网布局最优化模型。之后以成都市测震台网为例,经模拟退火算法求解,获得了分别满足重点监测区和非重点监测区地震监测能力需求的台网布局优化方案,明确给出了新增或新建监测台站的地理位置。

     

    Abstract: 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.
