【摘要】 以我国内陆软土为研究对象,在对内陆河湖相软土的分布情况及物理力学指标分析的基础上,提出了内陆河湖相软土区划原则及方法,将我国内陆河湖相软土在三个大区下进行二级区划,细化为八个亚区。同时统计了我国内陆河湖相软土的物理力学指标,分析各种指标的变异性和稳定性,提出以天然含水率、天然孔隙比、塑性指数、压缩系数和压缩模量五项指标作为内陆河湖相软土的鉴别指标。
【Abstract】 Referencing the research results of highway natural regionalization,combined with the natural condition of inland fluvial-lacustrine soft soil area,the secondary regionalization scheme of inland fluvial-lacustrine soft soil is proposed,and the secondary regionalization of inland fluvial-lacustrine soft soil is worked according to the topography,climate,regional geology,the geological structure and hydrogeology.Based on the collection and analysis for the physical and mechanical indexes of the inland fluvial-lacustrine soft soil,the variability and stability of these indexes are analyzed.It is turned out that the natural moisture content,natural void ratio,plasticity index,compressibility and the compressive modulus are chosen as the identification indexes of Inland fluvial-lacustrine soft soil.
