构造形迹 meaning in English
structural feature
Examples
- Discontinuities or weakness planes are those structural features which separate intact rock blocks within a rock mass .
不连续面或弱面指在岩体内分割完整岩石的那些构造形迹。 - The variation of regional stress field can be genetically interpreted by the rotation speed variation of the earth and its impact on the movement of lithosphere plate and deep processes of the earth , it is also related to the earlier structural feature and boundary of the basin
区域应力场变化可以用地球自转速度变化引起的岩石圈板块活动及触发的深部过程来解释，亦与先期构造形迹和盆地边界条件有关。 - 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。 - Depending on how the ground surface is denuded , the feature of the current crustal stress field and rock stress environment can be calculated analyzing the result in this paper : by analyzing the recovering feature of the elastic deformation of the rockmass in unload - stage under various pressures , it has been found there is close relationship between the recovering degree of the elastic deformation of the rockmass and the unloading degree of the pressure the direction of the major principal stress in the crustal stress field is not consistent with the direction of the crushing stress regional tectonics borne during the last tectonic movement . the evolving degree of the regional geomorphology evidently affects the current crustal stress field , which changes from the self - weight stress field to the horizontal stress field , with the changing of the eroding degree of the regional geomorphology ranging from valley area to hilly country to flat country . in valley area , where there is two stress belts , the bankslope s tress belt and the self - weight stress belt within the mountain . the direction of the major principal stress is nearly parallel to the ground surface and inclines towards the valley in the bankslope stress belt . it is nearly vertical in the self - weight stress belt
通过本文的研究成果，根据区域性地貌的演化特征，我们可以大致地对现今地应力场进行判断：在分级卸荷条件下，岩体中弹性变形的恢复具有明显的规律性，这种规律对于研究地应力场的演变是有帮助的；地应力场中最大主应力方向与区域构造形迹在最近的构造运动中所受区域性挤压应力的方向无明显的对应性；区域性地貌形态的演化程度对现今地应力场的特征具明显的影响，随着区域性地貌侵蚀程度由峡谷区、丘陵区、平原区的变化，现今地应力场特征由自重应力场、水平应力场为主含少量自重应力场特征向水平应力场的规律变化；在峡谷区，山体中具有两个应力带：自重应力带和卸荷应力带，最大主应力方向在卸荷应力带中近平行于坡面并倾向于河谷、在自重应力带中近于直立；根据原始地面遭剥蚀的程度，可以大致地估算最大主应力和中间主应力的量值和方向；在丘陵区和平原区，最大主应力的方向近于水平，并与附近区域性侵蚀盆地和河流的展布方向基本平行，根据原始地面遭剥蚀的程度，可以大致估算其最大主应力的量值；根据区域性地貌形态的特征来分析工程区的现今地应力场特征，并进而大致了解岩石的应力环境，这种分析方法得出的结论与许多实际的地应力测试成果基本一致，对于大型水电工程地下厂房和压力隧洞的设计是有所帮助的。 - The analysis of structural movement and expression shows that qinqi tectonic active area is a volcano - sendimentary compressional depression formed by several times of compression movement from lower proterozoic , and spreaded in the direction of north step by step till the forming of xiangshan and miboshan group in mid - later period of ordovician , bearing hardly with volcanical rock
从秦祁构造活动带的构造形迹分析认为，该构造带是自下元古以来多期挤压环境下形成的火山一沉积压陷，并一期又一期向北蚕食，于奥陶纪中后期形成基本不含火山岩的米钵山组、香山群压陷岩系。
