摘要
通过数值建模,定量分析"黄河海勃湾水利枢纽工程"水库蓄水,对乌海地震台体积式应变仪测值2015年1月—4月破年变规律形态的影响,按照地表载荷影响力学模型及岩层加载载荷形变机理计算,水库蓄水引起的应变量接近体应变实测值。由此确认,该工程水库蓄水对乌海体应变中短期异常变化具有较大影响。
Through numerical modeling,the impact of ＂the Yellow River water conservancy project Haibowan＂ reservoir water for the volume strain gauge measurements at Wuhai Seismic Station in January to April 2015 is quantitatively analyzed.According to the surface load influence mechanical model and stratum load deformation mechanism,the theoretical stain is calculated,and is closed the measured value of volume strain meter.It is confirmed that the reservoir water storage has a great impact on the short-term abnormal changes in the volume strain gauge of Wuhai Seismic Station.
