| 摘 要： | 工程反射地震常规的多次覆盖系统、排列和炮点的同时滚动,导致了施工效率的低下.为解决这个问题,从共反射点原理出发,详细探讨了非常规的移动炮点的多次覆盖观测方法,并与常规的多次覆盖观测方法进行了对比.认为这种方法在提高野外施工效率的同时,也可以提高数据的信噪比和速度分析的精度,并且可兼顾折射法和多道面波的应用.

| Abstract: | The conventional layout for CDP reflection survey in engineering geophysics,in which the receiving arrays and the shooting points are moving simultaneously,often causes lower efficiency.Based on the principle of common depth point,the authors present an unconventional geometry system in which only shooting points are moved.The geometry system is discussed in detail,and is also compared with the conventional layout.It is believed that not only increases the new geometry field work efficiency,but also could improve the data S/N ratio and the accuracy of velocity analysis.It can be applied in refraction seismology and multichannel analysis of surface waves(MASW)survey as well. |

| Keywords: | shallow reflection survey geometry system of moving shooting points conventional geometry system common depth points(CDP) stacking times |
