摘要
1995 年5 月2 日独山子南发生MS5.8 地震后,对独山子南部山区开展了GPS测量,自1995～1997 年共进行3 次复测。独山子GPS网共布设测点13 个,跨附近的一些活动构造断裂。所有观测量用随机软件进行了平差处理,最大相对误差为2.4×10- 7。独山子地区的活动断层总的活动特点是以逆断或逆掩方式为主,主断层面多朝南倾或近直立,四条主要断裂在两年来的活动速率为0.4～5m m /a。
A earthquake (M\-S 5.8) occurred the south of Dushanzi on May 2,1995,after which a GPS survey was developed in the mountain area of southern Dushanzi,and three times of surveys had been finished from 1995 to 1997.There are altogether 13 stations in Dushanzi GPS Monitoring Net,crossing some active tectonic faults nearby.All observed data had been done an adjustment processing;the maximum relative error is as much as 2.4×10 -7 .The active faults in Dushanzi move mainly in the way of thrust or overthrust.The principal fault planes mostly dip towards the south or near upright.The activity rates of 4 focal faults are more than 0.4 mm/a and less than 5 mm/a.
