本文通过沿海某工区的具体地震地质条件，应用浅层地震反射波与折射波法同步勘测新技术，采用合适的野外观测系统，全方位地拾取到反射与折射波信息，充分地利用这两种方法各自优点，较好地完成了工程地震勘查任务，取得较好地质效果。 Based on the specific seismic and geological conditions in a certain coastal area, this paper applies the synchronous seismic exploration technology of shallow seismic reflection and refraction wave, and uses the appropriate field observation system to pick up the information of reflections and refractions in all directions and makes full use of these two Methods, their respective advantages and better completion of the task of engineering seismic exploration and achieve better geological results.
