天津滨海新区软土微观结构试验研究

Test and Study on the Microstructure for Soft Soil of Tianjin Inshore New Developed Area

通过扫描电镜获取了天津滨海新区软土的微观照片,并用图像处理软件提取了软土孔隙的微观结构参数,研究表明,汉沽区、大港区和塘沽区的软土在组构特征上存在差异,这是导致其力学性质差异的主要原因。

Electronic scanning microscope is used to obtain the microscopic scanning picture of Tianjin soft soil, and picture processing software is used to obtain the micro-structure parameters. We find that it is different from the fabric character for Hangu, Dagang and Tanggu area soft soil. These differences result in the diversity of mechanical property.
