摘要
以甘肃陇东黄土为研究对象,通过野外勘察和室内实验,获得189组黄土土性参数数据。结合已有的区域地质资料,将获得的数据与国标《湿陷性黄土地区建筑标准》给出的指标参考值进行对比分析,并利用MATLAB软件进行指标概率分布函数的拟合与检验,判别各指标的分布类型。研究结果表明陇东黄土具有一定的特殊性,其天然密度较大,压缩系数较大,塑性指数较低。
Taking Longdong loess in Gansu Province as the research object,189 groups of loess soil parameter data are obtained through field investigation and laboratory experiments. Combined with the existing regional geological data,the obtained data are compared and analyzed with the index reference value given by the national standard"Building Standards in Collapsible Loess Area"and the distribution types of each index are judged by fitting and testing the index probability distribution function with MATLAB software. The results show that Longdong loess has certain particularity,which has higher natural density,higher compression coefficient and lower plasticity index.
