| 摘 要： | 传统观点认为北京土沟—高丽营一线的地裂缝是沿黄庄—高丽营断裂带由地面沉降诱发的复合型地裂缝,且地面沉降在地裂缝位错量中贡献率较大。本文通过对槽探、物化探成果和地裂缝监测数据的综合分析,认为黄庄—高丽营断裂的活动是该地裂缝形成和发育的控制因素和主要动力,地面沉降只是加剧了地裂缝发育规模和加大了活动速率,而非诱发因素,从而得出土沟—高丽营地裂缝属构造型地裂缝这一结论。

| Abstract: | It is known that Tugou-Gaoliying ground fissure is a composite one,which extends over Huangzhuang-Gaoliying fracture.Land subsidence plays a significant role in inducing the fissure and dislocation mainly.This paper puts forward that Huangzhuang-Gaoliying fracture plays a leading role in the formation and development of the ground fissure.Ground fissure is not the inducement,which just intensifies the scale and rate of ground fissure.Consequently,Tugou-Gaoliying ground fissure belongs to a kind of structural ground fissures. |
