摘　　要：扁铲侧胀试验(DMT)是一种先进的原位测试方法,近年来在武汉地区逐步应用。由于扁铲侧胀试验需要建立地区性相关关系才能准确测定岩土层主要参数,因此建立武汉地区扁铲侧胀试验经验公式尤显重要。文章首先介绍了扁铲侧胀试验基本原理,在参考国内外相关经验公式及大量工程对比试验的基础上,提出了武汉地区利用扁铲侧胀试验划分土类的标准,建立了土层DMT试验与静止土压力系数、压缩模量的经验公式。Flat dilatometer test （DMT） is an advanced in-situ measure method and has been gradually used in Wuhan city. It is very important to establish some empirical data about lateral expansion in this city because local relation in DMT can determine soil main parameters. This paper introduces DMT fundamental and then proposes the standards of soil classification using DMT based on the relevant empirical equations and many compared tests. The empirical equations about static earth pressure coefficient and compression modulus are also put forward in this paper.
