Optimal ApplicdCondition of Shallow Transverse-WaveReflection

hallow reflection-seismic exploration is one of the most important methods in engineering geophysical prospecting. Through the discussion of the longitudinal and transverse revolution of shallow seismic wave,the paper puts forward several ways to improve the detection of seismic reflected wave resolution. The authors discuss the relationship between seismic reflection factor and wave velocity distribution and state the importance of seismic wave velocity in engineering geophysics. A certain expression about the soft formation velocity and earth depth is especially given in this paper.On this basis,the authors emphatically study the rnerits and limits of the shallow seismic transverse-wave reflection method, and propose the optimal applied conditions of the method.
