弯曲测线多次覆盖方法,是为适应在地表复杂地区,例如在山区、林区、稻田、河网分布等地区开展地震勘探工作而提出的.因为在这类地区,直测线方法已遇到很大困难.弯曲测线方法,在国外,有的国家主要在地表复杂地区已开始作为一种实际勘探方法在使用了.但在国内,直至最近几年才开始在文献上出现.本文试图在已有的理论工作基础上,根据初步实践结果对方法作进一步讨论. The method of multiple coverage of the bent line is proposed for seismic exploration in areas with complex surface areas such as mountainous areas, forest areas, paddy fields and river networks, as the direct line method has encountered in such areas However, in most of the countries in the world, the method of curved line survey has been used as a practical exploration method mainly in complex areas of the earth surface, but it has not been reported in the literature in China until recently. Based on the existing theoretical work, the method is further discussed based on the preliminary practice results.
