地震折射法在深圳西部填海工程勘察中的应用
|
摘要
地震反射法适合于深部地层物性勘探,折射法适用于浅部地层中如地层面、断层面的界面解译,通过合理设计的观测系统和数据处理流程获取的数据,经解译处理后的地震剖面具有直观的层面特征。本文以深圳西部填海工程为例,采用浅层地震折射波法,揭示了场区范围内淤泥土层的分布和基岩面特征。
Seismic refraction method is suitable for exploration in deep strata properties,and shallow seismic refraction method is suitable to interpret the interface,such as the ground and fault.Through the design of rational observation systems and data processing to obtain the data processed by the interpretation,seismic profiles show an intuitive stratified feature.In this paper,taking an example of Shenzhen Western reclamation projects,the distribution of soil silt and bedrock characteristics in the field area by the use of shallow seismic refraction method are revealed.
