摘　　要：针对黄土塬地表复杂的特点,设计了符合该区施工特点的特殊三维地震观测系统,在施工过程中及时进行了炮检点的实时动态设计分析,采用激发点的灵活布设、检波排列的适度调整,较好地解决了CDP的分布以及资料的完整性问题。通过该方法的应用,首次获取了吕梁山脉中段西部一个典型的黄土源区地震反射资料,进而探索出了一套适合低信噪比、地表极其复杂的三维地震采集技术。In view of the complicated surface,a specific seismic survey that is suitable for the loess tableland is designed.The problems of array of shot points and geophone stations and integrity of data are successfully solved through real-time dynamical analysis of shot point and geophone station design,flexible array of the shot points and suitable adjusting of geophone stations.Meanwhile,solve the problem of the CDP of distribution and date of integrality. Through the methodological application,for the first tim...
