摘要:
甘肃祁连山主动源重复探测激发源位于甘肃省张掖市祁连山西流水水库,2015年7月9日各系统开始正式运行,11月10日完成了为期40天的连续激发实验。观测资料处理结果表明,气枪震源具有良好的一致性和可重复性,整个观测系统能比较清晰地记录到震源激发的信号。祁连山主动源项目建设取得的结果可为主动源探测工作提供宝贵经验和科学借鉴,不断取得的观测数据为跟踪了解祁连山地区的深部结构时空变化提供了可能。

Abstract:
The exciting source of the active source repeated monitoring is located in the Xiliushui Reservoir in Zhangye, Gansu Province. The system began operating normally on July 9, 2015, and we had completed a period of 40 days of continuous excitation experiment before November 10, 2015. Our results reveal that the airgun source has good consistency and repeatability, and the detective system of active source can record signal clearly. The construction of active source repeated exploration projects has achieved some results, which can provide valuable experience for the research of active source repeated exploration. The observation data we obtained makes it possible to follow the temporal and spatial variations of the deep structure of the Qilian Mountain areas.
