摘　　要：利用反射走时提出厂工程物探中浅层反射成像的新方法在局部范围内可将地层各界面视为平面，求取界面深度、速度诸参数，整个剖面的成像只需反复在局部范围内求解数值模拟表明方法具有精度高、收敛速度快等特点对清水江三板溪水电站坝址两个剖面的实际资料处理结果与现有资料吻合。Using reflection travel time, a new method for reflection image in shallow layer in engineerinmg prospecting is proposed. In the method, the formation interface in a small area can be considered as a plane, with the estimated Parameters such as interface, velocity and so on. The image of a whole section can be achieved only by making repeated solution in a small area. The nUmerical trials indicate that the method is characterized by high accuracy and fast convergence and so on. Qingshui myer in G~ Province coincide with data now available and Prove the method effeCtive in its application.
