摘要

该文利用单孔波速测试技术,对上海越江隧道工程场地作稳定性地质调查与评价。剪切波测试成果表明,工程场地属软弱场地土,场地类别为IV类;不需要考虑土层的液化现象;VII度地震烈度条件下,工程场地不会发生震陷问题;场地地脉动卓越周期为0．60～0．81s。
According to the theory of dastic wave, wave speed had a certain mathematical relationship with geotech-nical physical mechanics parameter when wave spread in layer. The wave speed testing technology in sin- gle - hole was just based on this theory. With this technology , the article made geological survey and e-valuate about site 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 it's 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 -0.81s.
