地震映像法在沌口长江公路大桥勘察中的应用

The Application of Seismic Imaging Method to Zhuankou Yangtze Bridge

地震映像法是目前水上勘探常用的方法,在内陆淡水与浅海地区有广泛的应用。通过对拟建中的沌口长江公路大桥桥址进行江上地震映像勘探,详细论述了水上地震映像的勘探方法。本次勘察查出断层一处,并初步查明了相关地质条件。钻探验证结果与物探资料基本一致,为拟建沌口长江公路大桥提供了勘察依据。

Seismic imaging method is widely used in water exploration,especially in the inland limnic and shallow sea area.This paper introduced water seismic imaging methodology by exploring the site of proposed Zhuankou Yangtze Bridge.It detected one fault and the relevant geologic conditions.The result of the drilling verification is in line with the geophysical data,which provides a basis for the proposed Zhuankou Yangtze Bridge.
