| 摘 要： | 城市大规模工程建设揭露了蕴含在土层中的丰富变形信息,调查发现合肥地区上更新统黏土中发育有数量众多的节理,节理成组产出,呈现不同交切、配套关系。通过对大量的调查数据进行统计分析,并绘制各调查点的节理玫瑰花图,将研究区内节理发育与断层分布逐一对比分析,结果显示合肥地区上更新统黏土中广泛发育的节理产状与场地附近的主要断层产状有关。走向玫瑰花图显示节理优势分布方位与场地附近主要断层走向近似一致;如果场地附近有多条断层交汇,土层中节理有以北西向较为优势的特征。

| Abstract: | Civic large-scale engineering construction disclosed rich information on deformation in soil layer.A survey found that there are a great number of joints developed in upper Pleistocene clay in the Hefei area,which occur in group,and in different intersecting and mating relations.Based on statistic analysis of tremendous survey data and the rose pattern drawn for joint at each survey point,this paper made a comparing analysis of joint development and fault distribution one by one,and results indicated that t... |
