摘　　要：为更好掌握花马湖流域软土的物理力学特性,通过扫描电镜观察、室内土工试验等方式,对该流域软土的矿物成分、微观结构、物理力学性质指标及各指标间的相互关系进行综合研究。结果表明:花马湖流域软土主要由伊利石、绿泥石等黏土矿物组成,呈致密块状结构,具有含水量高、孔隙比大、高压缩性、强度低、结构性强等特点;其孔隙比和含水量与其他物理力学指标间具有很好的相关性。研究成果可为花马湖流域地区工程的设计与施工提供参考。In order to better grasp the physical and mechanical properties of soft soil in the Huama Lake Basin,a comprehensive study was conducted on the mineral composition,microstructure,physical and mechanical properties indicators,and the interrelationships among diverse indicators of soft soil in the Huama Lake Basin through scanning electron microscopy observation,indoor soil tests and other methods.The research results indicated that the soft soil in the Huama Lake Basin was mainly composed of clay minerals such as illite and chlorite,with a dense block structure characteristics,high water content,large pore ratio,high compressibility,low strength,and strong structural characteristics.There was a good correlation between its pore ratio and water content with other physical and mechanical indicators.The research results can provide a reference for the design and construction of projects in Huama Lake Basin.
