SUMMARY

This research paper focuses on the development of ground motion models for simulating the main characteristics of recorded earthquake accelerograms induced by geothermal power plants (GPPs) operation. In this regard, firstly, a worldwide database for the GPP-induced earthquakes is gathered, containing 110 events and 664 recorded accelerograms. All the data are processed using a combined denoising method. Afterward, their main seismic characteristics are studied statistically, in both horizontal and vertical directions. Finally, different sets of ground motion models are developed for simulating the ground motion peak values, duration, 5% damped spectral acceleration and velocity in horizontal, and vertical directions.

概括

本研究论文的重点是开发地震动模型，以模拟由地热发电厂 (GPP) 运行引起的记录地震加速度图的主要特征。在这方面，首先，收集了 GPP 诱发地震的全球数据库，其中包含 110 个事件和 664 个记录的加速度图。所有数据均使用组合去噪方法进行处理。之后，对它们的主要地震特征进行了统计研究，包括水平和垂直两个方向。最后，开发了不同组的地震动模型，用于模拟地震动峰值、持续时间、水平和垂直方向的 5% 阻尼谱加速度和速度。
