本文用空间解析的方法讨论了炮点与接收点偏离指定位置所带来的旅行时时差,和先给定旅行时允许误差,然后提出求取炮点和接收点的允许移动范围的计算方法,从而为在山区地震勘探施工中进行合理偏移提供了理论根据。结合波动迭加加强之条件,还对弯曲测线资料处理中如何确定“网格”进行了必要的探讨。
This paper discusses the travel time difference caused by the deviation of the shot point and the receiving point from the specified position by using the method of spatial analysis and the allowable error firstly given when traveling, and then proposes the calculation method for calculating the allowable movement range of the shot point and the receiving point. Thus providing a theoretical basis for a reasonable offset in the mountainous seismic exploration and construction. Combining with the conditions of fluctuation and strengthening, it is necessary to discuss how to determine the “grid” in the data processing of curved lines.
