折射波法
折射法
Examples
- Standard guide for using the seismic refraction method for subsurface investigation
地下勘探用震波折射法的标准导则 - Probe into dissecting refraction method statics processing under complicated surface conditions
复杂地表条件剖分折射法静校正处理方法探索 - Seismic survey is a new method used to civil engineering area in recent years . it was widely applied to survey or detecting of roadbase , dam base , foundation of building , tunnel , river bed , lake bed and etc . the chief methods are reflection method , refraction method , wave velocity testing , surface ware survey and transverse wave suivey . seismic survey can divide different layer , measure the incidence of sediment stratum , detect the structure of rock , test the handle effect of surface wave survey , we can calculate the carrying capacity of foundation and other mechanical parameters . this technique can give service to some big engineering departments such as highway developing company , survey design company , water supply company , plan bureau , construct bureau etc
应用于工程的主要方法有反射波法折射波法波速测井面波法及横波勘探等。地震勘探能详细划分地层高精度地确定沉积地层的倾角能够准确探明岩体构造褶皱断层破碎带裂隙带对于回填工程路基坝基，地震勘探可以检测其回填处理效果对于隧道工程，可以探测隧道洞体的围岩分类及洞口地质情况利用面波勘探所得到的瑞利波速度，可以准确推算地基的承载力动弹模量等力学参数。
