【摘要】 基于拟建福厦高速铁路沿线软土地基工程的试验结果,分析了沿线软土物理力学指标的特性.通过十字板剪切试验,得知沿线软土的结构性强,以及部分地区软土具有膨胀性的特点.同时,软土的自由膨胀率与其他物理力学指标有着较好的相关关系,揭示了该地区软土特殊的工程特性.更多还原

【Abstract】 From the test results of soft foundation projects in the line of high-speed railway from Fuzhou to Xiamen, the characteristics of the physical and mechanical indexes were made a systematic study ; based on the vane shear on-the-spot test, the characteristic of strong structure of the soft clay in the line was reflected, and some area show dilatability, besides, coefficient of free swelling of the soft clay has good related to others physical and mechanical indexes, the special technical characteristics of mild clay were illustrated.更多还原
