| 强震动观测是准确把握强震动特征的最为科学有效的手段，强震记录的缺乏是目前雅鲁藏布江下游区工程建设面临的主要问题。本文分析雅下地震观测台站的布设现状，结合区域地震构造环境、主要断裂活动性特点，考虑雅下工程建设的需要，基于雅下工程场址地震动输入机制综合研究需求，提出雅鲁藏布江下游区强震动观测台站的四种布设方案。针对布设方案中满足最急需的原则，先期建设了米林、朗多、直白三个测点台站，并有效记录了2022年9月18日墨脱M3.9级地震、2022年11月10日墨脱M5.6地震，数据完整、可靠。研究将有助于今后逐步推进雅下强震动观测台站的建设，为雅下强震观测资料的积累及工程结构抗震设计地震动参数的合理确定提供支撑。 |

| Strong motion monitoring is the most scientific and effective means to accurately understand the characteristics of strong motion.The lack of strong motion records is the main problem faced by construction projects in the downstream region of the Yarlung Zangbo River.This paper analyzes the layout status of Yaxia earthquake monitoring station.Combining the regional seismotectonic environment, main fault activity characteristics, and the needs of Yaxia project construction, this paper puts forward four layout plans of strong motion monitoring station in Yaxia based on the integrated design principle.Three stations are arranged at Mainling, Langdo and Zhibai according to the layout plans, which have effectively recorded the Motuo M3.9 earthquake on September 18, 2022 and the Motuo M5.6 earthquake on November 10, 2022, with complete and reliable data.This research will help to gradually promote the construction of Yaxia strong motion monitoring station in the future, and provide support for the accumulation of Yaxia strong motion data and the reasonable determination of seismic design ground motion parameters of Yaxia project structures. |
