    北京市地裂缝分布与发育规律

    CHARACTERS OF THE GROUND FISSURES DEVELOPING IN BEIJING

    • 摘要: 近30年来,北京市人口急剧增多,城市快速扩张,地下水的抽取量逐年加大,地面沉降加剧,形成沉降中心,地裂缝活动性显著加强,成为制约城市发展规划的重要地质问题。目前,对于北京市地裂缝的认识仍然局限在针对单独场地的单一地裂缝的调查评价,缺乏对地裂缝区域性规律的认识。本文通过对有关文献和勘察资料的搜集汇总,结合现场调研,发现北京市地裂缝具有明显的地域性特征,大部分地裂缝的发育与深部断裂带的关系密切。据此我们依据断裂带与地裂缝的关系将北京地裂缝划分为6个区,对各区域内地裂缝的分布、产状、延伸以及破坏现象等特征进行了归纳,在此基础上对其成因做了简要分析,并对后续地裂缝研究工作的开展提出了建议。

       

      Abstract: In the past 30 years, the population in Beijing has got a sharp increase leading to the rapid expansion of the city, the extraction of groundwater resources increases year by year, aggravates the land subsidence, forms subsidence center, the activity of the ground fissures has significantly accelerated which becomes the important geological problem for the city development planning. At present, the knowledge of Beijing ground fissures are still limited to the investigation and evaluation of the individual space and a single crack evaluation, we still lack the understanding of the regional law. By collecting and summarizing related literature and survey data, conjointly fracture site surveying, we find that ground fissures in Beijing have obvious regional characteristics, the development of most ground fissures are closely associated with deep fault belt. Therefore, according to the relationship between the fault zone and ground fissures, the author divides the ground fissure zones into six regions, summarizes the distributions、occurrences、extension and the phenomena of destruction about the ground fissures, analyzes briefly about the reason of the ground fissures. Finally, several suggestions for future researches of ground fissures are put forward.
