扁铲侧胀试验在黄土地基评价中的应用

Application of flat dilatometer test to evaluation of loess foundation

根据扁铲侧胀试验在西安黄土地区的应用,对扁铲侧胀试验结果进行综合分析,完成对土类划分、重度、压缩、地基承载力的估算,同室内试验结果进行对比,找出产生差异的因素。结果表明:扁铲侧胀试验能较好得反应土体的连续性,其在工程中估算土的物理力学性质具有参考,并为我国黄土地区岩土工程勘察采用扁铲侧胀试验提供依据。

This paper introduced the application of fiat dilatometer test （DMT） in the loess area of Xi＇ an. According to the results, we made a comprehensive analysis and completed the soil classification, weight density, constrained modulus and the estimated bearing power of ground. Besides, we compared with the results of laboratory test and analyzed the factors causing the differences between the results. It showed that fiat dilatometer test can reflect the soil continuity better. The results offered reference for application of fiat dilatometer test in the loess region of China.
