崇州苟家特大山体滑坡地面振动特征

Characteristics of Ground vibration resulting from a huge landslip in Goujiashan,Chongzuo City

成都市数字化遥测地震台网比较完整地记录下了 2 0 0 1年 5月 2 7日发生在崇州苟家的特大山体滑坡主体滑动的地面振动过程。其记录波形明显不同于地震及爆破 ,具有一定的特殊性。由记录结果推断出滑坡主体滑动的起始时间是 5月 2 7日 0时 2 3分。

A huge landslip happened in the Guojiashan,Chongzuo City on 27 May 2001.The whole ground vibration procedure of main body was well recorded by the Digitalized Tele-metered Seismic Network of Chengdu.Its recorded forms of wave are not similar to the forms resulting from seismic or explode events.So it is a special form and is of important value.The starting time (local time) of the landslip is at 2001-05-27-00:23 according to the calculation of arrving time.
