| 摘 要： | 塌隐地裂缝，改变了地层的几何结构，破坏了三维地震反射层的连续性，出现了反射波同相轴错断、反射层产状变化、反射波能量转换、反射波增多或减少等特征。据此利用石塘湾因果岸三维地震资料对其地裂缝地质灾害形成进行了研究。通过对实际资料的分析，指出本区地裂缝类型为张跌型，并以较多的资料翔实地说明了诱发本区地裂地质灾害不可分割的五个因素，从而为治理地裂缝地质灾害提供了丰富的地质资料和治理方向。

| Abstract: | Subsidence and ground fissure have changed strata geometry and destructed continuity of 3D seismic reflecting horizon, thus, features of reflection wave phase axis staggered, reflecting horizon occurrence changed, reflection wave energy conversion, reflection wave increasing and reducing happened. On these grounds, we used Yinguoan 3D seismic data to study Shitangwan geologic hazard of ground fissures there. Through actual data study, pointed out the ground fissure in the area belongs to gaping and cascading down type, also explained five inductive factors of ground fissures in the area through studying full and accurate data, there by provided ground fissure harnessing methods and orientation with abundant geologic data. |
