北京市山前带宽线大组合地震勘探技术设想OA

Beijing is located at the northwest edge of North China Plain,surrounded by mountains on three sides.The mountain front belt is mainly formed by the combination of river alluvial fan and alluvial plain,which forms the geomorphological features of alluvial fan alluvial flood plain;At the same time,highways crisscross,transportation conditions are convenient,and the cultural environment is changeable.This special"double complex"seismic geological condition leads to the development of seismic data interference waves and poor imaging quality,which severely restricts the accurate identification of hidden structures and active faults in urban geology.Based on the practical effects of wide-line large combination project at Kuqa mountain front belt,this paper proposes a wide-line large combination seismic exploration technology for urban geological survey of Beijing mountain front belt.It is expected to reduce the level of acquisition noise,improve the quality of acquisition,obtain high-quality seismic imaging and comprehensive underground geological information,and promote further development of urban geology research.
