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。
Diced dilatometer test (DMT) is an advanced in-situ test method that has been gradually applied in Wuhan in recent years. Because the flat dilatometer test needs to establish the regional correlation in order to accurately determine the main parameters of rock and soil layer, it is important to establish the empirical formula of flat dilatometer test in Wuhan area. In this paper, the basic principle of flat dilatometer test is introduced. Based on the reference of domestic and foreign empirical formulas and comparative tests of a large number of projects, a standard for dividing soil with flat dilatometer test in Wuhan is proposed. The soil DMT test And static earth pressure coefficient, the empirical formula of compressive modulus.
