【摘要】 云南省曲靖市麒麟地区土层结构较复杂,相变频繁,各土层在岩性、厚度及空间展布和工程力学特征差异性较大,具有不均匀性,针对以往的岩土工程勘察中沿用的老方法对岩土参数取值的差异性,本文通过资料收集整理,用spss软件统计分析了该地区的一般黏性土即黏土、粉质黏土的物理指标间的关系,以及在直剪试验下力学指标与物理指标间的关系。得出黏土与粉质黏土的天然含水量与孔隙比呈线性增长关系,且相关度很高;这两种土的黏聚力与液限指数之间呈线性减小关系,且相关度较高;此外得出该地区土大部分处于可塑状态。文中所得出的结论对该地区地基承载力参数的选取具有一定的指导意义。更多还原

【Abstract】 The soil structure in the Qilin area of Qujing City,Yunnan Province is complex and the phase transition is frequent.The lithology,thickness and spatial distribution of the soil layers and engineering mechanical characteristics are quite different,which is inhomogeneity,and it is used in the previous geotechnical investigation.The difference between the values of geotechnical parameters in the old method,this paper collects and collations the data,and use spss software to analyze the relationship between the physical indexes of the clay soil and silty clay in the area,and in the direct shear test condition that the relationship between the mechanical index and the physical index.It is concluded that there is a linear growth relationship between the natural water content and the void ratio of clay and silty clay,and the correlation is high;and the relationship between the cohesion and the liquid limit index of the two soils decreases linearly and is related,the degree is high;in addition,come to the conclusion that the state of the soil in the area is mostly in plastic state.The conclusions obtained in this paper have certain guiding significance for the selection of the bearing capacity parameters of the area.更多还原
