| 摘 要： | 鉴于传统钻孔勘探确定淤泥层起伏情况的不足，在某一围堤水域地质勘察中利用浅层地震反射波法，确定淤泥层的起伏情况。从本场地反射波法物探映像图中可知．淤泥层与粘土层之间的界限明显，均在30s^-3左右产生了明显的反射波，且能清楚的看到基岩面的起伏情况。经过与钻探资料的对比发现，物探结果精度较高，满足了该工程的技术要求。分析表明，浅层地震反射波法是一种速度快、效率高的水域工程物探新方法，在各种水域工程的岩土工程勘察中有着广阔的应用前景。

| Abstract: | Because of the weakness in determining of the mud layer waving situation in traditional drilling exploration, we always use the shallow seismic reflected wave method in some retaining dike to determin the mud layer＇s waving situation. From the reflectional geophysical prospecting image of this water area, we know that there＇s a absolute line between slh layer and clay layer. There＇s a clear reflective wave in 30m, and it can be easily seem the moving situation of the bedrock surface. Compared with the drilling information, geophysical prospecting is more accuracy, and meets the requirment of this project. It shows that the shallow seismic reflected wave method is the fast, efficient new method in water project geophysical prospecting. It has the broad application prospects in a variety of geoteehnical engineering investigation. |
