构造结构面 meaning in English

tectonic discontinuity

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
摘要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。
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
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。
