摘要
通过对无锡轨道交通二号线施工区域的扁铲侧胀试验资料的整理和分析,结合国外的经验与本地土性,选择并建立适合本地区的公式,从扁铲指数获得一系列符合实际的土工参数,为设计提供依据。同时根据扁铲实验数据和静力触探试验的数据,通过线性分析、最小二乘法和回归系数的显著性检验,得出扁铲侧胀试验与静力触探试验的相关关系,供勘察设计时参考。
Based on data analysis of several DMT tests in the Metro Line Two of Wuxi, a proper formula was obtained in this paper for local application through combining the local soil characteristics and foreign experience. With this formula , a series of soil parameters from DMT indices could be inferred for design, And based on the data of DMT and CPT, the correlation relationship between DMT and CPT are concluded through regression analysis, least square method and regression coefficient of significance testing . These conclusions can be used for reference by the related designers.
