本文介绍一种有效的水域工程物探新方法——地震映象法,论述了其不同于其他地震勘探方法的特点。文中通过应力波在水下传播的原理,将振源方式和信号采集方式的要点作了阐述,并通过工程实例,体现了这种方法用于水域工程物探的有效性和实用性。
This paper introduces an effective method of geophysical exploration in water engineering - seismic mapping method and expounds its characteristics which are different from other seismic exploration methods. In this paper, the principle of vibration source and signal acquisition method are described based on the principle of stress wave propagation in underwater. Through the engineering examples, this method is valid and practical for geophysical exploration in water area.
