【摘要】 在对福建井水位观测值进行格值标定的基础上,分别对井水位、体应变仪、伸缩仪对四川汶川8.0级大震的体应变响应进行了分析。结果表明,上述3种观测系统的体应变响应约为10-7～10-8数量级,与月亮与太阳的起潮力所引起的二阶位的半日波的体应变相当。更多还原

【Abstract】 On the basis of the scale value calibration of well-water-level system in Fujian,the body strain responses of well water level,body strainmeter and extensometer to Wenchuan Ms8.0 earthquake are analyzed.The results show that all the response extent of above three instruments is about 10-7～10-8 which corresponds to the body strain of semi-diurnal wave induced by tide-generating force from moon and sun.更多还原
