摘要

在回顾分析国内外利用扁铲侧胀试验评价地基土性参数基础上，介绍了应用扁铲侧胀试验（DMT）和其它试验手段进行高速公路软土地基综合分析评价所取得的一些成果。根据扁铲侧胀试验结果估算的不排水抗剪强度与十字板试验结果基本一致，并能够反映土的强度随深度增长的规律，也分析了造成扁铲侧胀试验结果与室内试验结果之间差异的因素，研究结果可为扁铲侧胀试验在我国岩土工程领域的应用提供参考。

Abstract

After reviewing the research results and application of the flat dilatometer test (DMT) in the evaluation of soft soil parameters at home and aboard

authors introduced the application of DMT and other testing techniques to analyze the soil engineering properties of soft foundations for expressways synthetically. The calculated undrained shear strength based on DMT results is in accordance with that of field vane shear test (VST) basically; and the undrained shear strength from DMT also reflects the law of soil strength increasing with depth. Besides

the influential factors causing the difference between DMT and laboratory test results were analyzed. The results would provide reference for the application of DMT to domestic geotechnical engineering field.
