跨断层形变监测场地布设研究

Site Layout of the Across-fault Deformation Measurement

摘要:

从我国地震预报的紧迫性和跨断层形变监测短临预报的优势出发，发现目前跨断层监测网络布局的多个问题，并通过"面-线-点"的思路，对优化跨断层监测网络布局提出意见和思路，即以区域地震活动背景研究和活动断裂体系研究为基础，对相关断裂进行详细的分段性研究和活动性分析，然后结合现有观测场地的监测效能评估结果进行活动断裂调查，最终得出跨断层监测场地优化方案。

Abstract:

According to the urgency of earthquake forecasting in our country and the superiority of cross-fault deformation monitoring in short-term prediction, the shortcomings of the monitoring network layouts of current cross-fault deformations were found. Through surface-line-point me-thod, a method for optimizing the cross-fault monitoring network layout is presented in this paper. Based on the background research of regional seismic activity and active fault systems, detailed segmentation and activity analysis of the relevant faults are carried out. By assessing the results from the effective monitoring of existing observation sites and active fault investigation, an optimization scheme for cross-fault monitoring site is finally obtained.
