尤特莱奇大学的学生在1981和1982年暑假实习中用30公斤的重锤、12道加强式地震仪、自然频率为100赫兹的单个检波器,在荷兰三角洲潮汐平原作了6次覆盖的地震测线2600米,勘探深度为10至400米。潮汐平原由饱含水的砂子组成,没有任何风化层,为高分辨率勘探提供了非常有利的条件。震源产生的纵波峰值频率约200赫兹,垂直分辨率达3至5米,再加上横向分辨率也是3至5米,这样的资料质量就足以供地震地层学解释。
Utrecht University students in the 1981 and 1982 summer internships with a 30 kg hammer, 12 enhanced seismograph, a natural frequency of 100 hertz of a single detector, made six times in the Dutch tidal flat plains Earthquake line 2600 meters, exploration depth of 10 to 400 meters. The tidal plain consists of water-saturated sand and does not have any weathering layer, providing very favorable conditions for high-resolution exploration. The source produces a longitudinal peak at about 200 Hz, a vertical resolution of 3 to 5 meters, and a horizontal resolution of 3 to 5 meters. Such data quality is sufficient for seismic stratigraphic interpretation.
