常熟台倾斜仪降雨干扰定量分析

通过常熟地震台形变山洞内三套倾斜仪观测资料的对比分析,找到降雨、蓄水干扰对观测的影响,并利用弹性形变理论验证其可靠性,分析表明,每次强降雨均伴随有来自西南方向的倾斜干扰,其原因为雨水向湖中汇聚,水位上升产生弹性形变,从而引起地表倾斜.

Quantitatively Determination Analysis of Rain Influence at Changshu Seismic Station

Through distinction analysis against a life cycle observation data from the three inclinometers in the deformation cave of the Changshu Seismic Station,the paper found the influences of rainfall and water retaining.The paper validated its performance via elastic deformation theory.Results show that the declination influence from the west-south always accompany the torrential rains every time.The reason is that rain converges to lakes together.So the water level raising leads to elasticity deformation and ca...
