摘要
本文对大地坐标在主动源人工地震宽角反射/折射探测剖面各个环节中的应用分别给予了阐释.大地坐标贯穿于整个主动源人工地震剖面勘探工作中,从野外地震剖面设计、地震勘探资料成果计算、资料解释都需要大地坐标参入定位、换算、成果输出等.用Visual Basic6.0编写了大地坐标转换与直角坐标相互转换、桩号计算、炮检距计算等多方面功能的应用程序.该程序在地震宽角反射/折射剖面设计及资料解释各个环节中得到了广泛的应用,在人工地震地壳结构探测与研究过程中起到了重要作用.
We present the application of geodetic coordinates to active-source wide-angle seismic reflection/refraction profiles. Geodetic coordinates run through entire artificial source seismic prospecting profiles , which involve location, conversion and result output and so on, from the design for field seismic profile, result calculation for seismic prospecting data to data interpretation. The application program is compiled with Visual Basic6.0, including conversion relationship between the geodetic coordinate system and the rectangular coordinate system and calculation for stake and offset. The program has been used extensively in each aspect of the design and data interpretation in seismic wide-angle reflection / refraction profiles, which plays an important role in the crustal structure prospecting and study processes by the artificial seismic metod.
