According to the theory of dastic wave, wave speed had a certain mathematical relationship with geotechnical physical mechanics parameter when wave spread in layer. The wave speed testing technology in single - hole was valuate about just based on this theory. With this technology , the article made geological survey and esite steadily quality of cross the Huangpu River tunnel in Shanghai. Achievements in shearing wave test indicated that the engineering site belonged to soft site soil and itg dassification was grade IV, the site soil didnt need to be considered about liquefied phenomena; Subsidence problem would not arise by the condition of grade VII earthquake intensity ; the intrinsic period of ground pulsation in 30m depth was 0.63 - 0.81 s.
