悬挂式PS波速测井仪的应用

APPLICATION SUSPENDED LOGGER OF P AND S WAVE VELOCITY

本文除对悬挂式Ｐ、Ｓ波速测井仪作一简单介绍外，并对其测量结果作些讨论，如波速比Ｖ＿ｐ／Ｖ＿ｓ在软土层中的纵向变化，横波速度与标贯值Ｎ的关系，以及岩石井速度的特征。

Suspended logger of p and swave velocity is controled by computer.Most im-portant,the logger can measure on the spot wave velocity,and has a great improving formeasuring precision.Mean while,the vertical change of Vp/Vs in Soft soil layer,the relationbetween swave velocity and N(standard penetration test)value and velocity feature of rockwell were also discussed in this paper.
