摘　　要：为了评价断裂对场地的安全性影响,本文采用浅层地震反射波法,对原始勘探资料进行了校正、去噪、时深转换等处理,得到地震时间剖面,对其进行分析确定反射波组的地质性质,并结合地震深度剖面及钻探资料对其构造进行分析。浅层地震勘探结果表明:两条测线均未见有断层显示,在叠加地震时间剖面上,都能够清晰的反映出存在有3组较为明显的地震反射波组,在各个层位上,均未见有明显的同相轴错断现象。浅层地震反射波法在评价工程场地安全性中的应用效果显著。In order to evaluate the influence of fault on field safety,the shallow seismic reflection method is used in this research.Through correcting the original survey data, denoising and time- depth conversion, the time section of seismic is obtained.Accordingly,the geologic property of wave group reflection could be determined. Moreover,the structure is also studied by combining the seismic depth section and drilling data. The results of shallow seismic detection show that there is no fault in the field according to the two survey lines. But on the overlay seismic time section,the three evident seismic reflection wave groups are clearly showed. in each layer,the phenomenon of event dislocation is not significantly.
