土体新近纪构造结构面特征探讨

为阐明土体中存在的构造形迹对工程建（构）筑物地基的影响，将土体中的断层、构造节理和构造裂缝统称为土体新近纪构造结构面，用系统分析方法对土体新近纪构造结构面特性进行了分析。结果表明：土体构造结构面分布广泛且具隐伏性，是发震断裂在土体中留下的变形形迹，是近期构造活动最直接的反映，对工程地基土体的稳定性有重要影响。

Study on features of Neogene tectonic structure planes of soil mass

For better understanding the influence of tectonic structural features in soil mass to subgrade of infrastructure, the author defined the faults, structural joints and structural fissures as Neogene tectonic structural planes, and studied the features of the planes with the methods of systematic analysis. The results show that the planes are widely distributed and lie concealed, being the deformation traces left over by the seismological fault in the soil mass and in direct response to the recent tectonic activities, whice greatly influences on the stability of the soil mass as a part of the infrastructural subgrade.
