一、介绍我们收集了南北地震带上攀枝花、西昌、武都、高台等四个台的分量RZB型应变资料,并进行了分析。这些台使用的仪器都是高灵敏度的应变仪,能记录到固体潮的变化。四川攀枝花、西昌台地处南北地震带的中南段,甘肃武都台地处南北地震带的中北段,高台位于青藏高原东北缘的祁连山构造带上。这四个台南北跨越了近15°纬度区,东西跨越5°以上的经度区,控制区域大,基本能反映西部应力场的变化。这四个台的应变资料在2001年
I. INTRODUCTION We collected the RZB-type strain data of the four platforms in Panzhihua, Xichang, Wudu, and Gaotai of the North-South Seismic Belt and analyzed them. The instruments used in these stations are highly sensitive strain gauges that record changes in solid tide. Sichuan Panzhihua and Xichang are located in the central-southern segment of the North-South Seismic Belt and Wudui in Gansu are located in the central-northern segment of the North-South Seismic Belt, which is located on the Qilian Mountain tectonic belt in the northeastern margin of the Qinghai-Tibet Plateau. The four Tainan-North spanning nearly 15 ° latitude, east-west crossing more than 5 ° longitude zone, the control area is large, basically reflect the changes in the western stress field. The strain information on these four stations was in 2001
