波速扁铲侧胀试验(SDMT)在液化判别中的应用

摘要

波速扁铲侧胀仪(SDMT)是由标准的扁铲侧胀仪(DMT)和测量剪切波速Vs的地震测试模块组成.综合描述了SDMT试验方法,对SDMT和钻孔波速试验测出的剪切波速Vs比较,以及SDMT的液化判别初步分析.SDMT在南京的测试应用证明了SDMT的可靠性.%The seismic dilatometer (SDMT) is a combination of the standard DMT with a seismic module for measuring the shear wave velocity Vs. This paper summarized and presented a comparisons of Vs measured by SDMT and by other methods. It also illustrated the liquefaction potential of sands based on SDMT results and the applicability of SDMT in Nanjing area.
