用形变与倾斜仪方法研究了地壳形变 ,论述了仪器的技术特点、不同地质构造的形变台站以及形变记录的精度。对地震前形变干扰的识别进行了分析 ,研究了春、秋季间形变过程的季节特征 ,表明春季记录为引张形变 ,而秋季为压缩形变。 Deformation and inclinometer methods were used to study the deformation of the crust. The technical features of the instrument, deformation stations with different geological formations, and accuracy of deformation records were discussed. The identification of pre-earthquake deformation disturbances was analyzed and the seasonal characteristics of the deformation process during spring and autumn were studied. The results show that the spring records are the extensional deformation and the autumn compression deformation.
