隐伏溶洞是最常见的地质灾害之一，地震勘探方法是探测隐伏溶洞的有效手段，而数值模拟方法是地球物理正演模拟的主要方法，在地震勘探中发挥着重要作用。高斯波束正演模拟方法将波动方程和射线理论紧密结合，具有效率高、精度高等优点。采用高斯波束法对浅层隐伏溶洞的地震波场进行了模拟，结果表明，地震波场数值模拟可以有效地帮助我们在实际野外工作中进行观测系统的设计和优化。地震数值模拟技术的应用将大大提高浅层地震勘探的效率和精度。
Hidden cave is one of the most common geological hazards and the seismic prospecting method is an efficient tool to detect it. Numerical simulation method is the main method of geophysical forward modeling and plays a very important role in seismic prospecting. Gaussian beam forward modeling method combines the wave equation and the ray theory closely, and it has the advantages of high efficiency and high precision. We used Gaussian beam method to simulate the seismic wavefield of shallow hidden cave, and the results showed that the seismic numerical simulation can effectively help us design and optimize the geometry in actual field work. With the help of seismic numerical simulation, the efficiency and precision of shallow seismic prospecting will be improved significantly.
