Liangjia Village earth fissure, one of the 79 earth fissures along the Kouzhen-Guanshan fault located in the northern Weihe Basin, causes severe damage to buildings and farmlands. Since the late 1950s, 40 earth fissures have occurred in a similar east-west (EW) direction parallel to the Kouzhen-Guanshan fault, and a further 39 earth fissures have occurred with north-west, east-north, or north-east orientations intersecting the fault. In this study, a case study of Liangjia Village earth fissure was conducted to investigate the mechanisms of fissure generation in detail. Geotechnical and geophysical methods including measurements, trenching, drilling, and seismic exploration were used to reveal the basic characteristics, geological background, and origin model of the Liangjia Village earth fissure. This earth fissure, with a total length of 800 m in 2014, runs EW parallel to the Kouzhen-Guanshan fault, and it has damaged buildings and farmlands by forming sinkholes, gullies, subsidence, and a scarp. The trenching results indicated that this fissure underwent multi-phase activity. Analysis of geological drilling and shallow seismic profiling results showed that the fissure also possessed characteristics of a synsedimentary fault. Regarding its genesis, the fissure was formed through the combined actions of three factors: an earthquake created the fissure, the Kouzhen-Guanshan fault controlled its development, and loess erosion and groundwater runoff subsequently enlarged the fissure. Regional extension first generated many buried faults along the hanging wall of the Kouzhen-Guanshan fault before seismic activity caused the buried faults to propagate to the surface, where loess erosion and ground-water runoff promoted the formation of the current earth fissure.

梁家村地裂缝是位于渭河盆地北部寇振-官山断层的79个地裂缝之一，对建筑物和农田造成了严重破坏。自1950年代后期以来，在类似寇振-关山断裂的东西向（EW）方向上发生了40个地裂缝，并且西北，东西向或东北方向上又发生了39个地裂缝。与故障相交。在这项研究中，以梁家村地裂缝为例，详细研究了裂缝产生的机理。通过测量，挖沟，钻探和地震勘探等岩土和地球物理方法，揭示了梁家村地裂缝的基本特征，地质背景和成因模型。地裂 它在2014年的总长度为800 m，与东张口-官山断层平行延伸，并通过形成下沉坑，沟渠，下陷和陡坡而破坏了建筑物和农田。开槽结果表明该裂缝经历了多相活动。对地质钻探和浅层地震剖面分析结果表明，该裂缝还具有同沉积断层的特征。关于其成因，裂缝是由三个因素共同作用形成的：地震造成了裂缝，寇镇-关山断层控制了裂缝的发展，黄土侵蚀和地下水径流随后扩大了裂缝。
