【摘要】 以实例介绍了三维地震勘探测量中各项作业限差的关系、复测校差的关系以及测点坐标系转换关系。依照规范及限差控制标准,讨论了控制点布设、导线布设的精度计算以及作业方法。通过对极坐标法误差的计算论证了放样点误差主要是由测角误差引起。更多还原

【Abstract】 The paper introduced relations between tolerances in different operations,repetition measurement calibration errors and measuring point coordinate system conversion in 3D seismic prospecting surveying.According to criteria and tolerance control standard,discussed control point and traverse layout accuracy calculating,as well as operating methods.Through polar coordinate method error calculus demonstrated that the setting-out point error is mainly caused by angle measurement error.更多还原
