| 中文摘要: |
| 交城断裂带是晋中盆地西缘的主控断裂构造,也是地裂缝分布发育带。在野外调查基础上,开展交城断裂带中段地裂缝的构造控制效应研究,为区域地壳稳定性和国土空间开发适宜性评价等提供依据。研究表明,地裂缝沿构造的NEE向正滑段以及其与NE-NNE向构造段的结合部最发育,在NE-NNE向右行张扭段不发育。活动断裂是其旁侧或上覆的新生界沉积层中的地裂缝成生发育的主控因素,地裂缝是相关活动构造的一部分,断裂活动引起的局部应力场变化及相关构造影响控制了地裂缝的孕育、扩展和活动。地裂缝已成为沿线主要的地质灾害,对当地的城乡建设与居民生存环境造成了重大的灾害和威胁。 |
| 英文摘要: |
| Jiaocheng fault zone is the master western boundary fault of Jinzhong fault basin, and ground fissures around faults occur. Detailed field investigation and structural analysis to deal with the effect on controlling ground fissure of the middle portion of Jiaocheng fault zone to provide the basis for the evaluation of regional crustal stability and the suitability of land and space development. The ground fissures are usually developed around the NEE trending fault or occur at the linkage area of two fault segments. The origin and progressive development of fissures within the Cenozoic sediment cover are fundamentally controlled by active faults below. And ground fissures are part of the active structure. Ground fissures around faults occur because of stress concentration or to accommodate displacement variations along faults. And along the line, ground fissure has been the main geological disaster, causing significant damages and threats to local rural and urban constructions as well as the living environments of residents. |
