摘要 研究目的:基于扁铲侧胀试验(DMT)的基本原理,在理论上分析探讨通过DMT的A值的消散试验求解水平向固结系数的方法。同时,结合商丘—合肥—杭州(商合杭)铁路工程湖州试验段与上海—南通(沪通)铁路工程常熟试验段分别开展DMTA消散试验,对DMTA消散试验获取水平固结系数的理论和方法进行实例分析。研究结论:DMTA消散试验与孔压静探消散试验获取水平向固结系数很接近,二者在均质土层中相关性较好,在非均质土层中相关性较差;与DMTA消散试验及孔压静探消散试验获取的水平向固结系数相比,室内试验获取的水平向固结系数明显偏小,与其他研究者的成果一致。 Research purposes: Based on the basic principle of flat dilatometer test (DMT) , the discussion was made on the way for deriving the coefficient of horizontal consolidation from DMTA dissipation test in theory. As the same time , combined with the DMTA tests done in Huzhou experimental section of Shangqiu - Hefei - Hangzhou Railway and the Changshou experimental section of Shanghai - Nantong Railway, the theory and method for obtaining the coefficient of horizontal consolidation from the DMTA dissipation data were analysed by examples. Research conclusions:The results of the coefficient of horizontal consolidation were compared with CPTU dissipation tests data and laboratory odometer tests data. Comparisons of the results indicated that the coefficients of horizontal consolidation determined by DMTA tests and CPTU tests were very close. The correlation was good between the coefficient of horizontal consolidation determined by tests and CPTU tests in homogeneous soil, but it was poor in non - homogeneous soil. The coefficient of horizontal consolidation from laboratory odometer tests was smaller than those obtained by DMTA and CPTU test, and it was the same as that reported by other researchers.
