滩浅海海底高程测定方法
|
摘要
由于滩浅海高精度勘探方法的实施,传统的海底高程测量方法已不能满足高精度地震勘探的需要。本文详细地阐述了目前滩浅海勘探的高程数据测量方法;重点探讨了采用RTK实测潮高法在提高精度方面的作用和意义;详细介绍了滩浅海高程测量外业施工方法和内业处理流程;并提出了近海区域测深探头与GPS天线同步观测等新方法。
Since the high-precision beach-neritic exploration has been put into practice,the traditional sea-bottom elevation measurement methods did not meet the needs of high-precision seismic exploration.The paper expounded in detail the current elevation data measurement approaches in beach-neritic exploration,put emphasis on discussion of the role and meaning that uses practically measured tide height method to improve the precision,introduced in detail the outdoor operation and indoor processing flow of beach-neritic elevation and put forward the new approach of synchronous measurement combining the sounding searching unit with GPS antenna in offshore area.
