通过对北京地区地裂缝规模最大、致灾最为严重、具有典型特征的高丽营地裂缝带调查监测数据的分析,探讨了高丽营地裂缝带的活动特征,分析了该地裂缝带与地面沉降的相关性。该地裂缝受控于黄庄-高丽营断裂,具有断裂活动的继承性,具有以垂直变形为主、横向变形为辅的三维活动特征,地裂缝活动具有年际的周期性和年内变化的跳跃性,每年4-6月变形量占全年的60%-70%。高丽营地裂缝带上下盘的最大影响带宽度分别为49.5m和17.4m。研究结果为地裂缝地质灾害的防治奠定了基础。
通過對北京地區地裂縫規模最大、緻災最為嚴重、具有典型特徵的高麗營地裂縫帶調查鑑測數據的分析,探討瞭高麗營地裂縫帶的活動特徵,分析瞭該地裂縫帶與地麵沉降的相關性。該地裂縫受控于黃莊-高麗營斷裂,具有斷裂活動的繼承性,具有以垂直變形為主、橫嚮變形為輔的三維活動特徵,地裂縫活動具有年際的週期性和年內變化的跳躍性,每年4-6月變形量佔全年的60%-70%。高麗營地裂縫帶上下盤的最大影響帶寬度分彆為49.5m和17.4m。研究結果為地裂縫地質災害的防治奠定瞭基礎。

This paper outlines the distribution of a ground ifssure in Beijing. Based on research into the Gaoliying ground fissure and analysis of continuous monitoring data, this paper discusses the origins, periodicity, and the 3D activity characteristics of the Gaoliying ground fissure, and investigates the correlation between this ground fissure and land subsidence. This ifssure is control ed by the Huangzhuang-Gaoliying fracture, and fol ows its pattern of activity, with vertical deformation more important than horizontal deformation. The activity of this ground ifssure fol ows an annual periodicity, and deformation between April and June accounts for 60%to 70%of al activity each year. The width of biggest inlfuence area in the heading side is 17.4 m, and 49.5 m in the hanging side. The analysis shows that the Gaoliying ground ifssure is with the engineering disaster characteristics, including the similarity of engineering disaster, the limitations of disaster's width and the progressivity of geological disaster, and establishes the foundation of prevention and control on ground ifssure.
