| 摘 要： | 采用MSDP软件中的单纯型、HypoSat和LocSat定位方法,从震源深度及残差等方面,对比分析2014年大岗山水库区域内123次M_L≥2.0地震的定位结果,选择适用于水库诱发地震的最佳定位方法,并以库区17次定点爆破事件为例,验证最佳定位方法的可靠性。结果认为,LocSat定位方法更适用于水库诱发地震。

| Abstract: | By using the simplex, HypoSat and LocSat positioning methods in MSDP software, the focal depth and residual error are discussed. Comparing and analyzing the location results of 123 ML ≥ 2.0 earthquakes in the Dagangshan reservoir area in 2014, to choose the best location method suitable for reservoir-induced earthquakes. Taking 17 fixed-point blasting incidents in reservoir area as an example, than verify the reliability of the best positioning method. The results show that LocSat location method is more suitable for reservoir induced earthquakes. |
