摘要
地裂缝是地表土体在自然、人为因素的作用下,在地面形成具有一定长度和宽度的地表破裂现象。文章通过物理模型试验,重点研究倾角因素对正断型隐伏地裂缝向上覆土层破裂扩展的影响,结果表明不同隐伏裂缝倾角对地表的破坏不同,在剖面形态上也有差异,剖面破裂形态类型包括顺倾向、近直立和反倾向裂缝,力学机制主要有拉张裂缝和剪切裂缝。
Ground fissures are the phenomena of ground fissures with certain length and width caused by natural and manmade factors. Through physical model tests, this paper focuses on the influence of dip angle on the rupture propagation of normal-faulted buried ground fissures to overlying soil. The results show that different dip angles of buried fissures have different damage to the surface and different profiles. The types of rupture morphology of profiles include forward-dip, nearvertical and reverse-dip fissures, and mechanics. The main mechanisms are tension cracks and shear cracks.
